Game keeps crashing on me and it wont allow me to play the campaigne. The screen loads plays the vidio and then when Mack comes on it hangs and after about 30 secounds steam closes. Does anyone know if this is a known thing and if there is a fix. I've tried Validating the files it states one is missing then downloads it, it's not too spacific about which one but when the game is having issues were always hopfull when it finds something. Unfortunetly it didn't fix it and up on further testing "a" file is always detected as missing then is always downloaded so doubful that it has anything to do with why it hangs and crashes on that particular mission.
