think it had something to do with your ranking system think it whas in your string.ini file it involved changing the rank name or summit
EDit: i looked it up in my file think it whas ranklevelname i changed it to a diff name ones and i had the same prob it wouldnt go away even on new chars dunno what your file says but it is RankLevelName=%s in my files but then again i nevver worked it out
