I just got a new rig that came with Vista, and I can't connect to any multiplayer servers.
When I try to connect, I get as far as "Awaiting Snapshot" and then nothing. I can play off-line in the single-player mode beautifully (401fps in timedemo

I turned off UAC in Vista and tried several different compatibility modes. I even tried turning off McAfee's firewall, which still didn't help (some hacker's probably running up a big Best Buy bill on my card number now for that).
Anyone know how I could fix this?
Thanks
