hey guys DayZ has been working perfectly since i bought it a few days ago. i hopped on to play erlier and i got stuck on a black loading screen when i joined a server, and i had to close down and restart the game. this has happend 8 times today and still haven't managed to join a server and get playing. just before it goes to this screen i get an error message saying something about missing shotgun pellets or something. if anyone can help that would be awesome thanks
