ok so the thing is i already bought the game a year ago and wanted to play DayZ like everyone wants ;) so i bought Operation Arrowhead trough steam and i downloaded dayZ files trough SixLaucher but i keep getting this error Addon 'dayz_anim' requires addon 'CASigns2' and then i press ok and the game starts but then i get the error : no entry 'bin\config.bin/CfgVehicles/house.scope'. and then i press continue and i go to the servers and every server i go i get one of these 3 errors: 1. You were kicked by the game. 2. Files "C:\Program Files\Bohemia Interactive\ArmA 2\AddOns\a10.pbo", "C:\Program Files\Bohemia Interactive\ArmA 2\AddOns\air.pbo", "C:\Program Files\Bohemia Interactive\ArmA 2\AddOns\air2.pbo", "C:\Program Files\Bohemia Interactive\ArmA 2\AddOns\air3.pbo", "C:\Program Files\Bohemia Interactive\ArmA 2\AddOns\animals.pbo", "C:\Program Files\Bohemia Interactive\ArmA 2\AddOns\animals2.pbo", ... are not signed by a key accepted by this server. to play on this server, remove listed files or install aditional accepted keys.

3. Bad Version, Server Rejected connection.

The only thing I can suggest is reinstall Operation Arrowhead and run it before you attempt to play Dayz again. If you've already done this or it doesn't work.... I'm out of ideas.
