Please provide a lot more information such as the location of the files, your OS, etc Any error messages
The files are on my Time Capsule - I use it as a file server.
I am running Yosemite. 10.10.3
I don't remember the error message I received during the export, but now I just get the file is missing message.
Also - I just opened LR 5 and the images are there so that version didn't lose them.
However, the catalog is in the LR 6 version so won't work with the previous version.
"There are 838 and I have renamed them." Did you rename them outside of Lightroom?
no - I renamed them in LR
I think I may have finally recovered them, but I really think this is a bug with this version.
I had to update the folder location three times.
I had to sync the folder twice.
I had to re-import the catalog.
Now, I have to go through the images again and edit each one, but at least that's better than clicking each one and going through the painful process of finding it on my drive.
This has been miserable and I hope it doesn't happen again when I export! Or, when I rename them (which I have to do so they show up in order when I export them to Shoot Proof.
