Try, uh, the adduser, in a command line with a DOS window, then login.
world adduser eqemu eqemu 200
Then, try the 'world flag eqemu 200'. The account will already be set as a Server Op with the adduser command, but if you don't get an error when you do it, it may just work.
It may not solve your problems, so don't get mad at me if it don't.
