heh is problem is most likely something different...the problem you fixed 6 weeks ago....I fixed 5 months ago.....you forget I have hundreds of people playing with my version of the CoreLibrary these days
Darkman has reported the same type of problem with builde 227...He would load up on a co-op map about halfway and crash to desktop.
I tossed my network "TCPIP.dll" out the window and replaced it with the 227 TCPIP and dont have any problems any more but thats mb a totally different problem.
