Spring RTS Engine

Hey I'm new here. I think I have the wrong IP for server connection in the lobby client because It says I can't register an account in LAN mode. This IP may have come from me trying out PURE, after which I got the latest engine and BA. What should I do to reset it to the master server?

settings->server
taspringmaster.clan-sy.com port 8200

Thanks for getting back to me.
