Game crash at 1st July or 1st August

[unmerged(109609)]

Hi all,
I have a problem, when I start from The Grand Campaign I play normally till 30th July or 30th August 1486. When 1st of the next month comes the screen gets black and after a few seconds the Microsoft error screen appears. The error has is focused on EU2.exe and has attached a file (four random numbers and letters_appcompat).
I have Vanilla EU2. I've even tried to reinstall it, but that didn't help.

Thanks for any help

Can you post the last few lines of history.txt after such an error? Also, are you playing version 1.09?

It might also be useful to have a save from 30 July (or 30 August, if you can reach it).

Has this happened on more than one campaign?
