Cant get into Multiplayer servers

I cant get into any multiplayer server. I have it set to download anything I need but I cant because they arent "PURE" servers. Am I suppose to download every single mod out there? I even added a mod and it still wouldnt let me in. This is ridiculous!

Single player is good except for the glitch where sometime syou lose your saber.
