I created a couple of units along with the main one, and I moved the 3 units to the first enemy. I can get through the first combat, but it would crash on the next one. I'm not running it on any compatibility mode while on Windows 7 64-bit. When I tried Windows XP SP3 and SP2, it would actually crash more randomly.

If anyone on the same OS run it successfully, can I get advice on settings, etc? Thanks.

Edit: I just worked around it by moving 1 unit to the enemy.
