Have you tried a factory rest on the Spider Valve?
Hold down the A (or clean) button as you turn on the power and hold the button for 5-8 seconds.

If you have already tried updating the flash memory, and performing a factory reset without success, I would suggest that you have the amp serviced. You can contact Line 6 Europe for assistance, they can be reached at:
