USB Audio 2.0 MC Reference Design Driver Problem

[Manust]

Hello,

I finally got the USB Audio 2.0 MC Reference Design and tried to start using it.
First i flashed the newest binary into it - worked fine.

But with the Drivers there seem to be some problems.
When i install the Thesycon Drivers i'm only able to use Channel 1/2 with a maximum sample rate of 96kHz at 24Bit.
So I tried to install CEntrance drivers which show me "No compatible units connected"
After that i tried to install the Polytec Driver which doesn't finish installing becaus it can't find the Board.

I'm Running under Windows 7 Enterprise 32 Bit

Would be great if someone could help me, I can't find in the documetation something about this.

Greetings,
Manuel
