this just happened for the 4th time since last night. I'm flying along, fighting or whatever then *screeech* the screen freezes for 1-3 minutes with the same audio sample playing over and over. twice the game ended up crashing clear to desktop. one time the game came back after my plane had crashed. and this last time it came back just in time to display a connection lost message.
I'm running a P4 2.4ghz with 1GB PC2100 DDR, a Gf4 Ti4200, SB Live, and a fresh (as of sunday) install of XP Pro with SP2.
