Does this help me join these servers that's what I really want, they're the most populated when I go log on and and have pretty low lag for me so obviosuly I'd like to join and while I'm grateful for your help it doesn't seem like a solution.

Is there no way I can join these servers, why is that?
This seems kinda nuts I thought all I needed was Pak6-misc.pk3, perhaps a few other files that people would point me to a good location to get them and maybe a simple solution for the invalid game folder error.
