Whenever I leave a hanger or go to instant action the game crashes. Here are my specs:

Phenom 4 9500
3 gb DDR2 ram
Radeon HD 4870

Can you post the last few entries of the game's flux.log file please - will give us an idea what it's trying to do when it crashes.

You can also eliminate sound as a cause of the crashes by turning off sound in the flux.ini file (make a backup first).

Set the option:
disable_sound = 0
to:
disable_sound = 1

Save the file, and run the game. If it works then the game doesn't like something to do with sound, possibly a driver, or more likely an MP3 codec.

I launched the game's exe from the main folder and that worked. Thanks for the help though
