Re: Possible AMD driver bug causing Anti-Cheat bans.

I've had the exact same response! Bought a new 7600 and had Anti-Lag+ enabled. 

The customer service has been an embarrassing joke.

Refused to explain the ban stating they don't discuss 'internal procedures' the ban history webpage has the ban reason left empty.

So left in the dark and now every ticket is just a scripted response saying my account will not be investigated again. 

Valve have tweeted saying they will reverse the bans. 
I wouldn't hold my breath hoping EA will follow suit.
