I had that problem where continumm opens and closes rapidly, I did everything said in the post relevent to my situation. Now i'm trying playing on a guest account and it seems to be working, but it will not let me download the map files..or atlest I think that's what they are. it just closes and give me the error message Unable to create zone's\SSCU trenchwars\trench3.lvl , when trying to enter trenchwars zone.
