Try some general maintanance on your machine- update drivers, scan for viruses, close any other programs you may be running before you try and load PS...
What are your system specs? Perhaps you\'re running out of RAM. PlaneShift requires at least 256mb in most cases, although I highly recommend having more than this.
Have you tried checking each of the .part files with the MD5 sum checker tool, found at the bottom of the downloads page? Any corrupt files should be re-downloaded before you compile them and create the Setup exe.
Aside from that, I\'m not really sure what you can try. Good luck guys.
