Most recent Steam patch appears to make the June 29, DX9/DX 11 trainer crash to desktop upon activation regardless of where/when/how. Playing on my Sony VAIO VPCF115FM Gaming notebook - 1.6 Quad with TurboBoost. 1gb 330M Nvidia - Using the Sony drivers as the newest straight from Nvidia cause a flicker in most games. Win7 x64, Norton360 (disabled for trainer usage)- all legitimate programs only. All updates installed. I hope this is enough info. I've tried everything in the FAQ section with no luck. Perhaps this is something that you guys might be able to work around on your end? I mean...I did pay to be able to use these lol...it'd be nice to get to use what I paid for. THX!!!
