Uninstall all the QHY drivers, even if you need to do it manually..
Then install these (If you havent already)
http://qhyccd.com/ccdbbs/index.php?t...10476#msg10476 .
They will install on a 32 and 64 bit machine.
See how you go.
Failing this, the firmware may have been zapped, but it may be possible to reload the firmware.
Just depends where you got it from. Did you get it from me or elsewhere ?.
