xbox360 input stopped working

[gq-omistarz]

I'm confronted with a weird issue which I could not reproduce yet, because I can't fix it. Did anyone come across this before?

I used a FreePIE script to feed vJoy through an Xbox Elite Wireless Controller. I then reconfigured vJoy (vJoyConf.exe) to add more buttons, which prompted me to restart my system. That never happened before. After restarting FreePIE no longer receives inputs from the controller. Other FreePIE scripts still work fine. vJoy works too. The controller on its own works too, e.g. in games or the Xbox Accessories app.

I already reinstalled vJoy and FreePIE, but FreePIE still does not receive inputs from the controller. E.g. diagnostics.watch(xbox360[0].leftStickX) is always zero.

I have no idea what to do. I will not reinstall Windows because of this ;)
