If your power cord disconnected while you were using Premiere Elements, you MAY have a corrupted preferences file
Reset Corrupted Preferences = Press/HOLD Ctrl+Alt+Shift while starting program
Typically I start with lots and lots of questions to define the situation.
In view of the circumstances that you describe, I am going to start with a suggestion rather than questions. Then, if the suggestion does not work, then I will send a lot of questions your way.
Delete the Premiere Elements 11 settings file, named Adobe Premiere Elements Prefs. In Windows 7, 8, or 8.1 64 bit, the path to it is:
Local Disk C
and in the 11.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then delete the whole 11.0 Folder in which the Adobe Premiere Elements Prefs file exists. Be sure to be working with Folder Option Show Hidden Files, Folders, and Drives active so that you can see the complete path cited.
We will be watching for your results.
I see that John has posted a corrupted preference file suggestion using a shortcut. He and I appear to be on the same thought track, targeting the preference file. But, I would ask you and he to consider the non shortcut route to rule this troubleshooting idea in or out.
I would encourage you to follow through with the non shortcut route that I described to make sure we take care of the Adobe Premiere Elements Prefs file, and, if need be, the whole 11.0 Folder in which it exists.
Awesome thank you
Thanks for the follow up.
Looking forward to your results and thinking positive thoughts.
