Multiplayer causes instant crash

    I just upgraded my system and started out fresh. 2.4 quad, 750i mobo, dual 9600 gt oc sli, 320 gb hdd, 4 gb ram, windows 32bit. I of course have all of the up to date drivers and have added soase and entrenchment to my firewall exemptions. So I have fresh patched unmodded sins + entrenchment. I believe I can play single player, I can click multi-player and select a map and setting, as soon as I hit create, it forces a window and a minidump is created(And makes the error sound). Ive searched for a solution to this on google but every post/thread I find is about being so far into a game and it crashing. I cant even start it. I also tried putting resolution from max to normal, setting graphics settings to low and even windowed mode, no change. I already un/reinstalled the game with no result. Any useful information or a link to a detailed thread with a fix is appreciated.
