The problem could be a number of things and not necessarily FsP. You say FSX freezes after a time, so this could be high settings within FSX, bad graphics driver, faulty software, a bad tweak in the FSX .cfg, etc. Too numerous to mention really. Process of elimination will help with this problem. Does FSX run properly without FsP installed? Also, does FSX actually crash to desk top? If so, access the Event Viewer and provide the information from the event viewer.
