Hi Adam,
I have tried all the suggested fixes and although I had one day of smooth running, it has started crashing again.
please let me know if you need any other info.

Thanks

Thanks for the fast reply. Ill try those fixes.

Bought a joystick yesterday. Sad to see that this problem is over a year old

Same issue here:
Mine will work for a few minutes in a MP match then the joystick disappears.
