Okay guys, I have got the same problem. Here is my analysis (running Vista64):
1. Started W@W MP, received a firewall warning (suspect that Windows had a recent security fix); joined BK server and loaded to the 'Choose Team' screen. Crashed almost immediately.
2. Okay'd the firewall warning.
3. Disabled third LCD display.
3. Started W@W MP, joined BK server again, loaded to 'Choose Team' screen and crashed.
4. Checked punkbuster - everything up to date.
5. Started W@W MP, switched to Solo/Co-Op mode - I didn't have my disc to hand so just quit out of the game.
6. Started W@W MP, joined BK server, choose team and could play - no sign of crashing, however I didn't stay in for a whole game.
7. Started TS3 then W@W MP again. Game crashes, so I disabled the DirectX overlay plug-in. W@W works fine, I spec'd the remainder of the game.
8. Bad news, badkon currently is not working as it can't grab my IP address, so unable to warn any runners.
So, I think I'm cured ... just from switching to Solo/Co-Op mode.

BTW: I test software, applications, systems etc, as part of my day-job.
