With players having ongoing VOX lockups then game freeze up or crash, or Video lockups then game freeze or crash. If possible coad the game so the executable can be run in a debug mode where if an ingame event happens to lock your system a dump file of your system memory will be triggered the same way a BSOD does.
Then you can zip it up and make Skuzzy's life even more misserable.......
Or the other way around is HTC creates a debug version of the game that they mail you if your problems are frequent enough.
