How do I fix this error, Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modal session requires modal window'?

I have been trying to start up my Batman: Arkham City game recently and it says that it cannot open and gives me this error;

"Terminating app due to uncaught exception 'NSInternalInconsistancyException', reason: 'Model session requires model window'"

I have played the game for about 13 hours before this error started to pop up and I was wondering if anyone knew of a way to fix it. Any information would be greatly appreaciated.

MacBook Pro, Other OS, Version 10.9.2

Yesterday I had the same problem.


I installed the game and played for five hours with no problem but in the last execution my iMac show me that error. I tried to uninstall and install the game again but always show me the error. I did the same with the Steam client with no solution.


Finally I fixed the error deleting a folder.


Go to Macintosh HD/Users/[username]/Library/Caches/com.feralinteractive.bmac

and delete the folder named "com.plausiblelabs.crashreporter.data"


Try to launch the game again.


Good luck.
