I just took a peek at the unreal engine forums to see if there was any reports on the engine crashing with the latest drivers .which i immediately regretted as this is the place where everyone that's doing something with ure4 comes to ask help with their problems. Can't seem to find anything that directly relates to us tho. I think the best thing to do is try Rumbaars solution and contact BE customers support and report the crashes. They might already be aware of any problems and able to give you much better advice than i can. keep that crash report .. they might want to have a look at it.
