I have the same problem. Around 39.000 pictures in my catalogue, even newly imported folders with about 400 pictures in it do not work!!! Smaller folders are displayed correctly.

Windows 7 64 bit. Previous LR version: 3.4.

This is just unbelievable that this wasn't found during beta-testing. I will not play around with any workarounds but expect Adobe to provide an update asap. It is really annoying to pay for an update and then have to work with the older version.

I too have the same issue.  Also, it seems slower than LR 3.

I have 250,000 photos, this is very frustrating

yes - unbelievable!

I can't understand this...... Adobe is losing my sympathy!

I agree, no patches whatsoever and they appear not to care at all that you lose any publish information on keywords as long as you can export from one catalog and reimport it.  Sad.  The last time I contacted them, they had their response down to a routine.  Still no patches or admission that there is a problem in the catalog conversion routine.  They also keep replying to my open ticket trying to get it closed, but offering no solution except the workaround.  You all need to open chat with Adobe or call them if you are having the issue.

Appreciate the update Ben. Perhaps someone needs to share/discuss this perspective with the folks at Chat and that manage the tickets.  Respectfully, while you had said there is a problem and that you would update this thread with more info 10 days ago, it's not clear to me where you are at in the chain with Adobe.  So while you've said there is a problem and it is being worked on, you have a completely different story than we are getting in feedback from support. My experience is almost identical to Kevin's (zdybkela) above.

So, I'll retract my statement of "No admission, there is a problem..." Clearly, you agree there is a reproduceable issue, but I cannot find where Adobe has indicated they have a problem unless you are speaking for Adobe.

My statement was based on responses I have received in Chat in relation to my two tickets. Responses to open tickets that do not address the issue but that seek to close a ticket with a workaround is poor PR and leaves the impression that everything is just fine.  When I asked to speak to a manager, my request was denied, my ticket closed. I'm not looking for a blow by blow, but a lot of Goodwill could be obtained if the folks at Chat and Support could at least indicate that the engineers are working on a solution and that there is currently no ETA. Even an update on the LR Support page would probably suffice for most.

The standard response that we need to create a new catalog and import the old one, even though we have repeatedly said this is not acceptable with no recourse and closing of the chat sessions is wrong. It does not help that Scott Kelby/Matt Kloskowski and other big proponents of LR continue to rave about the product and indicate that they've had "No issues".  Seriously?  If we're using LR and can reproduce the issues for you, we're not noobs at this.

A quick look at the "Hot Issues" reveals no mention of catalog conversion fail: http://blogs.adobe.com/lightroomjournal/2012/03/lightroom-4-hot-issues .html

even though it is discussed by consumer feedback recorded in the journal. Then, no more journals since the 12th.  Not sure where we should get our info from, but it is difficult to find what is being done about the catalog conversion errors. Is there some place we can see what is being worked on and monitor for status, or are we supposed to keep hitting chat and our tickets?

To my knowledge you seem to be the only one that indicated you can reproduce the issue, but I have no idea who you are or what is being done about it other than what we get back through chat sessions, and it ain't pretty.  I spent well over 60 hours of my own time trying to fix things and get my catalog working again. I'm finally up and using LR4 and now I'm dealing with how LR4 handles things much differently in the color reproduction and the conversion from ProPhoto to sRGB.

Adding my voice from another thread on this topic.  After ~12 hours trying to make this work, which included worthless help from Chat Support and an hour on hold then a worthless 1.5 hours of telephone support I got a refund for the product.  When this gets resolved I'll consider trying again, but more likely give it some time to see what other bugs are being discovered by the Adobe test organization, aka the LR user community.

Same symptoms - collections, published services, previous import...all showed thousands of photo's - but nothing in the standard folder in the library module showed nothing.  Selecting a photo in a collection and moving to the Develop module worked, as well.

Thanks Adobe for getting this fixed.

I just had this issue myself. I'm glad I came here first before doing anything drastic, like uninstall and reinstall. I'm in the process of downloading LR 4.1RC, and hope it fixes my problem. I hadn't noticed anything wrong untill this afternoon. None of my previews were displaying. Only thing that I can remember doing since the last time I ran LR4 was install the OnOne LR Presets. I'll report back later as to whether this fixes it.

Well...I installed the LR 4.1RC and it still doesn't display any previews. I even created a new catalog and re-imported all my photos, almost 14k worth, and it still won't display any previews. I'm now having it generate standard previews, and this is taking forever! If this doesn't work, I'll have to seriously think about upgrading the ram in my iMac and start using Apeture!

Anyone else still having problems after installing the update?
