Make sure it's allowed as client in MediaMonkey (Tools > Options > Media Sharing) as well as that you have some content shared with it (either through the global server settings or the custom client settings (if enabled)).

I use MM and have access with a stand alone Hifi-Musicplayer. Everythin is fine.
Problem is with a sattelite settop box which works fine with other UPNP server (Fritz-Box), but not with MM.
I can see the MM server. If I open it I see the folder, which is empty.
Where is the problem? Is it the firewall? Or a access problem?
Who can help me?
