Alright here we go, Was playing the game one day, like around October 5th. Was thrown out of the server with a message with something like "invalid military skin" (it was involving British armed forces) and after trial and error i got the pre-game server list to load up (the one that has every ones names) then when i tried to play i got global ban, something like, #60___. Now, I have a few buddies that were big enough assholes to try to be script kiddies, and were complaining afterwards about a #3000 type ban, I've never heard of #6000. After then re-installing thinking battle eye is trolling me somehow (happened before saying global ban # then all blank) I couldn't even load up the game, it saying "bad serial number". Now I am re purchasing the game, as DayZ is is sorely missed. But right now I'm asking if there is any other way to protect my game. Never touched download links, (only thing I've even downloaded since summer is converted youtube videos) have asshole friends, but all of them retarded with computers. Also information on #6000 ban would be nice, and I'm just assuming bad serial number is something to do with me and my special self, and anything thing I should stay away from (like skype, vent, teampseak, etc.). Oh and didn't post this before as, my mindset was Warz will hold me off till the stand alone. Oh god how I was mistaken. Then went on vacation. Any help as I have said, would be great.
