So it looks like a few of us have been encountering this issue with the videos that cause the system to freeze up. In another forum I notice that Tom reckons nothing has changed in the way videos are handled in GameEx, but it seems strange that many are having the same issue on systems that were previously working since a few updates ago. Tom, If there's anything I can do to shed some more light just let me know. BTW I found that having GameEx running in a window and not hiding the desktop makes it easier to shut it down without restarting the system.
