What are you doing when this message comes up?
Has this version of AE ever worked on your system?
Does AE CC 2014 still work on your system?
I close AE with task manager, when this message comes up.
I have not any problem with AE CC 2014 about this.
But This version (2015 13.5.1) have this problem when I used persian fonts for my layer's names.!
I research for resolve this problem. somebody tells clear some fonts; example Arial MT... but I see this message yet.!
I would suggest you work in CC 2014 for the time being. AE CC 2014 can open files saved with AE CC 2015 with no problem.
If you already removed CC 2014 from your system, don't worry; it's easy to install it again.
And I would recommend filing a bug report so that whatever is causing your problem in the new version can be fixed! Feature Request/Bug Report Form
