Michele, you're installing the wrong driver!
You've gotta choose >>Diamond Viper Pro 9100<<, _not_ the 9000 driver. The Pro
9100 doesn't even use the .ini file anymore.
Maybe the latest r4 drivers either don't have the Pro 9100 choice or the new
code is bad. At any rate, mine is version 1.0.3.P1 and works wonderfully. I'll
be glad to send it to you if you want…
