Okay i managed to log in to this server so yeah follow the steps that ive listed and you should be fine.
Download the ML setup [ takes ard 20mins ]
And get the patch from the same website.
Next run the setup you find in the ML file.
Extract the patch into the folder u save ML in [ should be something like C:/programfiles/GameFlier/ ( some funny characters ) ]
A icon will automatically be found on your desktop, run that icon and your game should start.
What icon did you use to open ur game?
There's afew icons that can be used to open the game but only one leads to the private server, so you gotta use the correct one
If you are unable to log in, it probably means that the server is down.
Anw you have to extract basically everything into the same folder and den run the patch and enter the game via the new icon on ur desktop.
PS: Leroy are you using vista? you might wanna try running in admin
