Keep getting punkbuster kicked for corrupted memory

[Inazuma]

Hey everyone,
Trying to play Call of Duty 4 and WAW. COD4 was fine... until I installed WAW it seems. I get kicked for "Restriction: Corrupted Memory" within the first few minutes of joining a game (usually within a min). As far as I know, my RAM is fine; I get no errors anywhere else.

Im running Windows 7 RC 7100 64bit.

Yep I've tried updating PB with pbsetup.exe (it updated fine, but I still get kicked), and also tried setting the cod exes to admin rights.

Edit: Sorted the problem I had to close Fraps - it also sorted out my mouse lag issue!
