go to steam library, go to dayz properties, click local files tab, and verify integrity of game cache. this usually fixes this

Sorry since I didnt put what I already tried.

1.I have verified my files countless times (No difference)
2.Un-installed DayZ
3.Manually changed files in the Battleye folder that may have been corrupt (However some of the files in that folder have a winRAR sign onto the left as the image,not sure what this means)

And also I have tried joining a Battleye protected server which my friends were on too see if the game would install it for me but that didnt work
