sigma saves us etc etc

so this bug is starting to get on my nerves a bit so i installed 1.5 and 1.5.1 using gigs torrent i think and around turn 6 on any faction it crashes or when a battle is loading ive looked around and ive seen threads about fixes but they dont seem to work for me unless ive installed them wrong so can anyone provide me with some answers

You remembered to disable the UAC if you're using vista or win7, right?

um no
