I am trying to install everything as I was told, arma 2, arma 2 ao, arma 2 beta, dayz commander..... when I try to update wrong cd key, wrong key given on setup, connection lost, no message received, connection to host lost, session lost..... 1. Did the suggested find AO folder with regedit: NO folder can be found. 2. Tried to do delete the beta folder, and download the patch manually (wrong cd key error) 3. tried validating game files, 14 files failed to validated reaquired, twice in a row. Steam is running as admin... I have no idea what's missing, cant update, can't do a single ....blasted thing.... I keep searching through the forums, yet no fix for my many many issues, and you cant tell me I have to reinstall everything, because it took me 36 hours to download everything Arma2, Arma2AO, DayzCommander, im running on 3mbs.... So you guys have to find a way to fix this without having to start all over again... because this is some serious BS.... I HAVE NEVER in my life came across something so freaking difficult to play, it's almost as atrocious as Steam and Arma 3.... always giving issues with connecting with friends, or playing online ...it's redundant. Anyways, Ill keep searching and trying everything I can find. without having to uninstall everything and downloading it again....
