Try reset your preferences
If that doesn't work.
Uninstall the plugin - and try it again.
If symptoms persist, try trashing your prefs again.
If it works ok then try reinstall the plugin.
If the symptoms return contact the plugin vendor.
Did all of the above to no avail. Now waiting on Adobe "Escalated" support to call and an answer from the plugin maker.
I got an email from Adobe Support with the solution. Here it is and it worked:
If you have 64 bit computer, navigate to the below location.
C:\Program Files(X86)\Common Files\Adobe folder\SL Cache folder.
Move the contents of SL Cache to desktop.
Click on Start button, type %appdata% and press enter.
You will be able to view Roaming folder.
Click on 'Appdata' in the address bar , open Local/Adobe folder.
Locate the folder named 'AAMUpdater' and 'OOBE' and rename it to AAMUpdaterold' and 'OOBEold'.
Once you are done with the above steps, click on Start button>All Programs.
Locate and launch the Creative Cloud desktop application.
Then try launching the Creative Cloud products and check if you are able to launch the products without any issues.
I was not able to rename the OOBE folder, but the process worked any way.
