Trying to run Cosession on Lenovo Thinkpad T500 with Windows XP

Performed Custom Install with remote only and only serial connections. It seemed to install alright but the program wont run. I get a "csw caused a general protection fault in module csw.exe at 000f:00af" error. If I try running it a second time it wont do anything. If I reboot and try running, I get the same error.

I have installed Cosession numerous times on other computers and have never had a problem. Not sure what is going on.

Any suggestions would be appreciated.
