Hi there!
I've got huge problem here. I had to delete Arma 3 from disk becasue of low memory on C partition, and decided to reinstall it on disk D. After deleting mods to avoid some of the issues and downloading game again, there's a error which appears every single time after launching a game in launcher (doesn't matter if 32 or 64 bit version). Also tried to run game as administrator, and it doesn't help either.

(I know it's in polish, but seems like error code wouldn't change because of that :P)
I'm sending you a ZIP file with report and dxdiag.txt. (it's on zippy, because I'm not sure how to upload files here >.>)
