So, check this out. I have two computers in my house that my daughter and I have been playing wolfteam on for about a year with no problems at all, other then lag disconnects. Well about a week ago the older single core computer running windows 7 home 32bit started with the S19 GameGuard authentication failure, it was out of the blue. My computer to this day is still running strong, which is a quad core, windows 7 premium 64bit. We have the same firewall, anit-virus, ad aware and spybot. Well I got pissed she kept getting disconnected so I was like "I'll fix this stupid error!!" So I formatted the hard drive and reinstalled windows. I ONLY had wolfteam installed on the computer and got into a game....about 35-40 min in BANG S19 GameGuard authentication failed!!!!
Figure that crap out!!
I am now at a TOTAL loss with that computer, while mine is just fine.
