Sound FX Dramas

[Darbzy]

Hi all,

Apologies if this question is addressed elsewhere on this forum, but if someone could help me I'd be most grateful.

I recently downloaded COD through steam and the game worked great. I also wanted to play online so I downloaded and installed the Team Fusion patches v3.00 and v3.01 to enable multiplayer and this went okay too, however my sound effects seem to have reverted to an earlier (and very crappy) version. Is there an easy way to fix this? I'm no expert with computers so detailed instructions would be great.
Thanks in advance,
Darbzy
