This used to happen only on quit, as described here: http://forums.adobe.com/message/5806716#5806716
It also would happen if I started up AE by double clicking a project file, as opposed to launching the application, then opening a project file once the application is open. In this case, the error message would continuously pop up after hitting OK, preventing me from doing anything. I would then have to force quit.
Now, I am completely paralyzed because no matter what I do, I get this error as soon as I open a project and no matter how many times I hit OK, it keeps popping up. I then must force quit every time. AE is completely useless at this point.
I have tried reinstalling (preferences as well) to no avail. Totally stuck here.
