Check your MFD throttle. Do you see a profile listed on the lcd? I have a feeling no, because somethings up with the drivers and the x52. I was able to use the smart software back before I disconnected. I can't now figure out what it was the proper match for drivers and S6 smart software profiler. All I could do was use the older drivers I posted and sst. Otherwise, the profiels woudl not load and I would get the the no profile, not a dat file error message. And no profiles woudl load onto the MFD throttle (x52). The file format changed too yo can see in the .pro or .dat extension. Along the way, I totally unistalled and reinstalled my loystick drivers with still no luck. It's the kind of thing where the later drivers ask for more hardware than the X52 really has, and so doesn't load properly becasue it's lacking chips or something. I'd love to be proven wrong but after a week wrestling with it it was a no go without rolling back to older drivers.
