DOW II audio prevents game launch

Bakon

When Launching DOW II and DOW II - Chaos Rising, I receive this message:
A recent Games for Windows LIVE update is causing a crash in Dawn of War 2 when using LIVE voice chat. We are currently working to resolve this issue and apologize for the inconvenience. In the mean time, please disable voice chat to continue enjoying Dawn of War 2.

The problem is, my computer does not have Games for Windows LIVE.

When I launch Retribution:
It appears your game is crashing due to an audio related issue. Please ensure your audio drivers are up to date.

If you continue to experience this crash, try running the game with the launch option "-nosound".

And I did, and it launches when I launch it with "-nosound" on, but I obviously want sound to be on when I play. I'm not sure what to do.
