Plutonium

I am not running afterburner or anything with an overlay either.

When I try to run a lan game it crashes after another player connects
using host computer custom games xpartygo
client computers connect then the ip
the 2nd player can sometimes make it in just long enough to walk around
sometime crash before it gets all the way logged in
