Star Wolves 2 problem

[AThinker]

Bought myself the Star Wolves trilogy on the recent Steam sale (really wished SW1 carried over to SW2), and have beaten SW1 without any problems. Get to SW2, and all of a sudden, my frame rate drops during my first major battle. I chose to fight aliens, instead of doing a mission for the guy that sold me the ship.

Worst of all, right after I beat them back into their portal, and exit into Haeon(?), I pop up right next to the trade station, as opposed to popping out of the portal. At this point, it won't let me exit, nor buy/sell at the trading post.

Has anyone found a way to fix this issue, or could provide a link? Google is not being my friend at the moment.

My specs are:

Windows 8.1 64-bit
AMD E1-1200 APU with Radeon(tm) HD Graphics (2 CPUs), ~1.6GHz
6144MB RAM
MD Radeon HD 7310 Graphics
