Trying to get on multiplayer, I need some help.

There's a DL on steam community http://steamcommunity.com/sharedfiles/filedetails/?id=217050930 that's supposed give you a new server list. But when i click it it brings me to a blank page. I've tried using another tutorial that has you change stuff in the game files, I'm not to good at doing that kind of stuff and failed miserably, And the only video on youtube explaining how to do this was in Italian. Can someone do me a huge favor and explain to me like I'm five how to get multiplayer to work.
