5.0 won't play sounds on mediabay

Hi,

I just moved from my mac laptop (MacBook Pro 32bit) to a Windows7 64 bit.
I installed Nuendo 5.0 and scanned my library disk with Mediabay, but it won’t playback any mediafile.
All my library is made of .mp3 and Broadcast Wave files .wav.
None of those is being played back.
On my laptop Mac is fine and working.

Any clue?

Many thanks.

Check, if the ‘control room’ is set up correctly.
If it’s active, deactivate it for testing.

Is it not even playing back or are you just not hearing it?
