Your save file doesn't crash for me at the end of the turn. However, I did notice two problems with the file:
1. The graphics for the captured Pirate bases are corrupt.
2. When I contact Svensgaard, I get a message that something is wrong with the faction text file.
I started a new game as Aki-Zeta that included Sven. I didn't get the error msg when I contacted Sven. Your Pirates.txt file may be damaged or contain invalid entries. I suggest that you restore it from the installation CD. That probably won't fix the current game, though.
Also, if you have a dual-core system, it's normal for SMAX to use 50% of the CPU. It uses 100% on single-core systems.
