HELP! New Pioneer 1.21 Firmware has Broke My Pioneer 105

I upgraded the firmware on my Pioneer 105 from version 0.52 to version 1.21, Everything appeared to go fine, but now when i try to record anything using nero or Prassi dvd all i get is a message saying waiting for drive to become ready

The drive is still recognised in xp and plays cd and dvd’s fine i just cant burn anything

I cant flash the drive back to 0.52 so what can i do…?
