SolvedBattleye Ban?

Hey guys, I tried playing DayZ after not playing it for a couple months, and when I clicked on a server it said I had a Battleye Global Ban.

I've played DayZ before and this never happened, and I've never hacked on it in my life, or tried to download any software to modify my game. Is there anything I can do to get unbanned or do I have to buy a new key?

I'm also on DayZ standalone.

New key for you!

Changing CD-keys does not work anymore go ahead and buy a new pack of arma 2 and arma 2 oa on a new steam account
