recently upgraded to 6.4.0.7788 game guard that runs with continent of the ninth finds a suspicious program and faults the game back to the desktop with riva up and running. disable it and no problem playing the game.. no problems with my previous version which i can't remember the version number
Why do you post it here instead of GameGuard support forums? The anticheat's approach is based on whitelisting publicly known overlays, so simply give them time to recognize the update, analyze it and add to the list of allowed tools.
just trying to be helpful in providing info - i did email xigncode log files to inca who does the game guard thing and webzen who provide the game.. 6.2 works fine - thx for the riva tuner software!!! sorry if i posted the info in the wrong forum
