I installed UT (the first one --- Plz don't confuse it with UT2003 or 2004) It ran well even under WinXP SP2 !!! But suddenly, after some weeks, It showed up an error that something was wrong (It said something about Terrain (as far as I remember (I don't have a good memory))) It failed 2 open since then even in the safe mode ! So I reinstalled ! That fixed IT ! But I had to play the for the championship all over again ! Can any1 help me ? at least tell me the cause !
