Well hello there... Some may remember me as Seere/Youknowme and various other silly names, anyways I want to start mapping again or release the .map files of my past maps but since I got a new comp and Vista

I can't seem to run mohaa-tried the usual as in run it as admin/compatability blah blah but no success.
I get to the loading screen then recieve the "moh has caused a problem",
I have heard that moh doesn't like new drivers but how do I go about getting old drivers whilst I have Vista?
Any help for an old school mapper would be very much appreciated
