i have looked at this thread http://www.unrealadmin.org/forums/showthread.php?t=8060 but all my settings are identical and still does not show on server list.
i also tried the deleteing of MasterServerAddress=master1.mplayer.com MasterServerPort=27900 from the ini but still nothing , im sure the problem is elsewhere. :[
yes i have "Advertise server "checked .
any one got a clue what i should try? i want to run dedicated on #2.
