GNET "failed to add server" everytime

I'm running the GNET simple example:

;Simple gnet demo
;
;Check out www.blitzbasic.com/gnet/gnet_servers.php while running!
;

Include "gnet_inc.bb"

my_game$="My_Game"

;ping!
Print "Ping:"+GNET_Ping()
Print ""

;list active servers
;
ListServers()

;add a server!
;
Print "Adding server..."
Print ""

If Not GNET_AddServer( my_game$ )
	RuntimeError "Failed to add server"
EndIf

;list active servers
;
ListServers()

;refresh server!
;
Input "Hit return to refresh server..."
Print ""

If Not GNET_RefreshServer( my_game$,"New Server Name!" )
	RuntimeError "Failed to refresh server"
EndIf

;list active servers
;
ListServers()

;remove ourselves!
;
Input "Hit return to remove server and exit..."
Print ""

If Not GNET_RemoveServer( my_game$ )
	RuntimeError "Failed to remove server"
EndIf

End

Function ListServers()
	If Not GNET_ListServers()
		RuntimeError "Failed to list servers"
	EndIf
	
	Print LSet$("Game",16)+LSet$("Server",32)+LSet$("IP",16)
	Print String$("-",64)
	For t.GNET_Server=Each GNET_Server
		Print LSet$(t\game$,16)+LSet$(t\server$,32)+LSet$(t\ip$,16)
	Next
	Print ""
End Function

and its giving me Failed To Add Server everytime. I'm a client with a stable internet connection so I dont see whats wrong. It worked before.
