I installed OEM Win7 64b bit all MS Updates to date as of 8-13-2010. MS Firewall and Defender disabled. Nod32 as antivirus, disabled during game play.
Last week Friday I was having constant AH executable unrecoverable errors to the desktop while playing in the blue arena with the updated Mindinoa map. Every 15-20 minutes. The errors happened during furballs with a large amount of VOX chatter. Noticing that it was happening during a peak sound event, I changed my sound setup ing the game. I stopped having the executable error to the desktop, or at least I was able to play for an error free hour then moved to the orange arena with no errors.
Original sound setup from the clipobard:
Master Volume
