Topic: No Sound with FF800 + two Inputs not working

Since i installed Windows7 Home Prof. (64Bit) i got a problem with my FF800. Sometimes there no sound. I have to switch the FF800 off and on again to get a working sound. Sometimes the sound disapears when i'm working in Cubase, but most of the time it's not working after starting Windows.
I'm using the latest Firmware and driver. Is there something i can do to get the FF working?

And two Analog Input are not working. Can it be repaired or do i have to buy a new one?

Bye
Dennis
