Exception when trying to connect to port in use

[oaeide]

Receiving "Unhandled Exception: System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted". This should be allowed for the multicast listener.

Can probably be fixed by setting ReuseAddress=true or something of the sorts - i don't really write c#, so I don't know the exact fix.
