I would say that 99% of the crashes are a result of parsing errors. The biggest one i have fixed so far is the user name parsing. User names were not being parsed correctly. Also captain zyrain or any other admiral is being listed as a planet

which might cause the data file to get corrupted.
if you consistently crash about 15-30 seconds after starting attac, most likely, it is the data file corruption, delete the game and recreate it.
try and pinpoint the crashes. i am working to fix them all. When i tested attac, i did not have alot of data to work with gamewise. i am playing at the stardock now, so i am getting alot of good data and making alot of little parsing fixes.
depending on what i find, i might try and release an update next week. why dont you email me and i can try and get you a version before then so see if the fixes i made fix your problems. (only the two postees)
earth.
