When you register with HonoredSoft's game server, please use !regaccount to create a username and password. Because we're on a dynamic IP, client GUIDs may change occasionally. When that happens, only accounts that can !loginaccount will be able to re-associate with themselves.
Alternately, you can set cl_guidServerUniq to 0 (seta cl_guidServerUniq "0") before you !register so that your GUID does not change when our IP does.
