I have an x55 but my understanding is that it all works the same.
I would recommend you delete your user folder, and restart SC. It will recreate the folder. Then place the xml in the proper place and do your key bindings. Sometimes things just get garbled.
If after this it still is creating problems I would PM via forums Blaze (blaze9119) or talk to him on mumble. If you see Jay online you can always ask him as well as Joshua, I believe they have the warthog. I’m not sure who else has one, but just ask on mumble as someone can assist with this if you are still having difficulties
