The first thing that I would do is create a new, current System Restore Point, in case you need to get back to today.
Then, reboot to Safe Mode and choose System Restore, choosing a point back when things worked, as they should. Test. If we get lucky, then things will likely work fine. If not, then nothing lost, as you have the "current" Restore Point.
This morning, when i tried to start Adobe PE 7, same thing happened. Looked like it loaded my project, then just disappeared.
Task was running, when viewed from task manager. I looked everywhere on screen, even under the task bar.
Tried closing and restarting, on luck. Tried a different project, again no luck.
Then tried minimizing then maximizing the running PE7 from the task manager. That brought the project back up.
That brought up a full screen preview, then I went to menu windows->restore workspace. (Then Saved the project)
I hope this helps. cecilg
Just an update...I installed the latest version of Quicktime and all works
Great news, and thank you for reporting the fix.
I continue to have this problem. And I've already tried updating Quciktime which did not solve the problem. I also do not have any malware or software that is conflicting, nor have I made changes to my system that would cause this to happen. The software works fine for a time, then upon exit or sometimes crash something happens to the project file and when trying to reopen it just stays minmized.
The only solution I have found is deleting the project file and starting over - a major loss of work and time.
I am a software developer myself and this problem reeks of file corruption, possible due to a handling or auto-save issue. I appreciate any help or other suggestions not already tried, but this really does feel like a bug.
Using i7 Extreme processor
2TB HDD with 1.5TB free
Win7 Prof edition
all latest drivers and firmware
If repairing your licensing, as suggested above, doesn't solve this problem, Bishop, you should advise Adobe of this bug.
