DVC2 512

[musicmasterward]

I connected my DVC2 512 to my Windows 7 PC (32 bit). I can see the DVC is connected in my properties, and it does work when I test it in the Tools.exe application, but I can't see it in the Daslight 2 app. I already restarted my PC and reinstalled the software but it won't work. What can I do or what am I doing wrong?
