I need you guys help, i just downloaded arma 2 and arrow head. i played arma 2 but it was very slow. i started updating and installing and uploading stuff that i thought was getting me day-z. im half way through the process but i hit a snag. i have six launcher and six updater installed. I have day-z commander installed. i accidently started all of this before starting arrow head because i fought it would lag. i now get something called failure to connect to key server. im am not good with computer at all but i keep getting other messages like something about a CD drive?Also it says bad serial number when i try to connect to day-z. it wont connect to arma 2 arrow head, only arma 2. it also wont connect to day-z. im so far deep in programs that im about to launch my computer across the room> URGENT HELP.
