new cddrv.sys ver # 5.0.2195.1620

The new driver has a different version # and description.
I copied this new driver to c:\windows\system32\drivers to test it out. The error message I had before was gone but I got an 'I/O error' message instead. So far, so good.
Next, I upgraded to DV2_209 and restarted PC.
Checked firmware with IAA (Intel Appl Accel). It says 2.03
Ran upgrade again, same results. Is my Optorite defective?
