I had similar problem, lights on shifter were blinking and wheel couldn't calibrate itself.
Wheel worked again after changing power adapter (found similar one in my workplace)

In 2 weeks there will be next race,probably in cooler conditions but with hotter street tyres,join us then!

I'll be there!
