Minecraft Forums

I have already reinstalled minecraft and have deleted my .minecraft folder but I saved a copy of the old one. When I log in I click play, multiplayer, join server, then when it's supposed to be joining...it instead closes out and takes me back to the screen with the play button again. I do not know what wrong. I was on Evolve and it told me firewall was blocking games and I have made it so firewall is not affecting it anymore. So any suggestions on how to fix this problem? Or a link to where I can find the solution. Thanks for the help.
