Mezzmo does not show any media

Everyone seems to like Mezzmo a lot, so I blindly bought it, without testing.
I am using Twonky and several other Media Server on different machines without problem, but this installation of Mezzmo makes more trouble than good.
At the end it show that it enumerates my media, and the property pane shows some meaningflul values, but it does not show the media to my players, e.g. Windows Media Player, permission are all set to share everything to anyone. I even traced it with Wirehshark and Mezzmo really tells, there is nothing:

...
<NumberReturned>0</NumberReturned>
<TotalMatches>0</TotalMatches>
<UpdateID>0</UpdateID>
...

but there are tons of data. Is Mezzmo such a mess? Or did I overlook a checkbox?

Debugging? Is active, but without showing meaningful data
Total size of all sqllite DBs: about 500 MB

Any ideas?

Can you please turn on logging (see this thread: http://forum.conceiva.com/showthread...nostic-logging) then try browsing that empty folder again and once no files come up please stop the server and send the logs to support (at) conceiva (dot) com - I'm sure we'll work it out.
