You have already got a user name and password to use with Mariusnet. Now go to http://projectmagma.net and get the latest patch for Myth II. After you've installed it, open the game, click multiplayer, click "Servers" and change it to Mariusnet, then enter your username and password to log in.

well, i've tried to thoroughly search posts for something that parallells my situation, but i still can't figure out what's up. I have the latest (1.6) and i registered, but i'm having login errors in mythII multiplayer login. I've put all the files where they're supposed to go... what's the deal?
[even though i'm selecting marius.net, its telling me "bungie.net does not seem to be responding at this time" when i attempt to log in]

man i'm so slow in the head. i had deleted ALL of these files except bungie.net DNS of the plugins. thanks for the guidance.
