Consistent Crashing

  I have had this game for a while now, and I love it, but it crashes all the time. Heres my debug 

http://pastebin.com/XQVgTcMc   I searched for the zip file in program data and there are about 4 of them but none dated to the incident.  The crashes happen randomly, but more often than not in battles.   I can start a new game and it will happen immediately.  Or I may be lucky and get an hour at most at times. I have just updated my video driver.  The game version is 1.50.  And I might add that I have lowered the settings for this game to a ridiculously low level.
