After approximately 5-30 mins of play, Dayz will either crash in two ways. 1st: with a Windows error message of (to the effect of) "Dayz has encountered a Data Execution Protection and has been closed". 2nd: The game will freeze and wont respond to any keystrokes, I then need to turn off the PC with the power button and reboot. This did not happen with the launch build of the game, however the last two patches appear to have made it worse. Windows Vista.
I have tried to disable DEP however this error still occurs.
