I have a new system with windows 8.1 RFactor2 demo installed. Logitech g25 is recognized in game but had no force feedback. I tried version 5.10 of the Logitech gaming software, but it pretty much gave no response at all when trying to get a profiler to open. I finally managed to get a profiler software to setup by using version 5.0 of Logitech gaming software. The profiler opens, but it does not have a visible window, so I can not make any adjustments in the profiler. I do now have force feedback in the game. Any advice or suggestions on how to get the profiler visible?
