UED Locks Up Whole Computer...
Ok I've been mapping for some time now and have never had serious problems with UED. But recently I just formatted my Hard Drive. And reinstalled UT and UED. I noticed I don't have Unreal.exe anymore but I think I had it last time because I installed UT with an older disk. I have all the bonus packs and everything. Now when I load UED and map a little every once in a while it locks up when I'm in 3d view and moving the camera backwards.
Also I switch video cards but I updated all the drivers and everything and it's my original card cause the new one didn't seem to load UT fast enough and wasn't using its on board memory. But UED used to work fine with this card. Anyone know how to help?
