I run a vanilla minecraft and a Voltz server, but i cant get the big dig server to work no matter what i do. Does anyone know of a tutorial somewhere?

Ah did not see the all the launcher errors i will just wait it out and try later. also i have redownloaded the launcher 3 times so it is not that.

Ok, so I tried to install optfine into the Voltz modjar, and it did not work. So i deleted the all of the launcher and all of its files. I then tried to reinstall everything, and now when the launcher loads it does not show any mod packs and will not let me sign in. HELP!!!!
