Problems solved with Adobe Chat. Installed Adobe Application Manager 8.0 and YES!!! - no problem with reinstall!! :-)
Thanks for reporting your Premiere Elements 12 and 13 issue and its solution. Great contribution. Was the fix of updating the Adobe Application Manager
applied to just version 13 or to both 12 and 13?
If you work with 12 instead of 13, please update 12 to 12.1 using an opened 12 project's Help Menu/Update.
I ran into a Premiere Elements 12 install/Sign In issue which was also resolved by updating the Adobe Application Manager.
Congratulations to you and Adobe Chat on a job well done.
