I am having the same problem. No one has helped me figure it out yet :/

I too am experiencing the exact same problem. Has anyone from Adobe contacted you guys directly with any resolution?? I haven't found any posts on here for any form of solution. Re-installing does nothing :/ If it means anything, I am not running any form of Firewall. I am on a home computer connected directly to an Apple Airport.

Exactly the same thing is happenng to me. And not matter hwo much I ask none of them have fixed this problem yet!

Someone PLEASE fix this problem!!!

Corey,

I am expierencing this error when I try to launch/sign into Muse. When I attempt to sign in it shows the 2nd screen frozen. Then after a few moments it goes to the grey Error screen. And I have been turning on/off my firewall for days and playing with the settings to no avail.

I couldn't find those documents on my computer that you mentioned before, and I have no idea what is casuing the problem.

would be extremly kind if somebody could solve this issue! its doing my head in not being able to use this cool programme.

Yes using mountain lion. Any idea when we will see this fixed?

I'm having the same problem (lowerr screen) running Lion 10.7.3

Hello!

I'm having the same problem!!!!! This is what I get...

I'm running Lion 10.7.3

I'm getting the same error as the OP. But I'm on Windows 7 64-bit. To be clear, I'm not getting any error message. The Sign In box just turns darker and freezes.

I'm trying to get it to work on my personal computer but it works fine on my work machine which is on the same network and also runs Win 7 64-bit.

I too am having a similar problem.  I have a Creative Cloud monthly subscription.  Here is what happens with mine:

Endless Sign In Loop:

The problem was first encountered when I tried to start Muse from my desktop. It would prompt me with a pop-up screen that says "Further account information is required to use Adobe Muse. You will need to sign in to continue." So I would click "next" and see the "sign in" area was already populated with my Adobe ID (my email address) with the password field blank.  So I enter my password and click "sign in" and it cycles like it's trying, and then just takes me right back to the first screen "Further account information...... etc etc" and it just goes in a circle like that.

I tried searching for help on the forums, but the closest thing I could find suggested that I maybe the problem is that I haven't logged into Business Catalyst yet, so I tried logging into BC via Dreamweaver, and that gave the exact same cyclical event as above with Muse.  

I have talked to someone on Live Adobe Help Chat twice.  The first time they told me "this product is brand new, and some kinks are being worked out, just wait 24hrs and try again." I did that, it didn't work. The second time, the conclusion was to refer me to the Business Catalyst Help.  Did that, and they told me to try and close the pop up screen and go to "help" in adobe and deactivate.  Can't do that because I can't get past that pop up sign in screen.

I am on a Windows 7 machine, and I also checked to see if I have the opm.db file, and I do.

Things I've tried:

• Resetting my password. Didn't work. 
• Uninstalling and reinstalling.  Didn't work.
• Uninstalling, downloading trial version, installing with the hopes of at least getting into the app and then activating, and that didn't work.  Same cyclical log in as mention above.

I am paying for this service, and am eager to use it!

Thanks James,

Your colleague Zak Williamson got to me first with an answer which perfectly corrected everything, which is in line with what you are saying here.  Maybe this info will help someone else, as well.

Here's his response to my other post:

Please delete the "MBLStore" and "OOBE" folders found in

 

on Mac: <yourusername>/Library/Application Support/Adobe

on Windows XP: <youruser>\Local Settings\Application Data\Adobe

on Windows 7: <youruser>\AppData\Local\Adobe

 

and delete the "AdobeMuse" folder found in

 

on Mac: <yourusername>/Library/Preferences

on Windows XP: <youruser>\Local Settings\

on Windows 7: <youruser>\AppData\Roaming

 

Then launch Muse. It will go through the first launch experience of asking for UI language, AdobeID, etc.

How can you deactivade MUSE if  I can not log in in first place... I don't have that choice of deactivated... This is really anoying and a big problem for my bussiness... please help.

Problem with Adobe Muse Login solved! >>>opm.db<<<

Dear James Boag,

thx for your entry. I had also the above mentioned repeating trouble with the login for Muse, then I searched for the opm.db file and deleted it as you mentioned. Problem solved! The opm.db file must have been corrupted. Now Adobe Muse works just fine!
