Assuming the runuo server you are running is on the same computer you are useing to try and log on with??
Fire up UOG and in the top right side is creat localserver
enter ip 127.0.0.1
Also try this link
http://www.runuo.com/forum/showthre...ight=ServerList
download the
serverlist file and put it in place of your original one (best to make backup of original one first)
You can find your original one in C:\Program Files\RunUO Software Team\RunUO 1.0 RC0\Scripts\Misc
Once setup , start server and you and your friends should be able to have fun
