From this pc, for me the ss is way 2 dark (can only see hud, and the stats below), is that the problem you get when you're shot?
If it is... well, i just gotta say it's really a strange bug :/
Did you try reinstalling FPSC (uninstall, delte FPSC folder, and reinstall), installing the latest FPSC patch, making shure you have the latest dx9 version (september or october, dunno wich month is the latest one), updating latest drivers for graphic card, making shure you got SP2 of winxp, etc.?
Perhaps this might help, if it doesn't, well, we just have to wait until someone knows what else to do.
My love is seperated in 2 parts, 1 of them is 3ds Max 7, the other; FPSC.
