Lag in attack of B-team

[jdud10]

So I have a very serious issue with attack of the b team. Whenever I try to play the FPS drops to 1. what strikes me odd is when my menu is open i get a good 100+ FPS. The menu is open when the server is running on LAN so the world would be doing all the stuff minecraft world do. Mobs are in the background moving around in 100 FPS while i am stuck in the menu ;(. any ideas???
