Mac server creator problem

It seems for me that the server hosting app for mac is broken in 0.6 as I cannot host a working server anymore.

The server is on the masterlist, no firewall problems detected, port forwarding all fine but when anyone tries to enter it (including me), we time out.

This problem started happening at 0.5.2 trunk but it wasn't such a problem then because I could just use the 0.5.2 original server creator to host the server.

Can anyone help me fix this?

Thanks
