Uh... Did I do that?

I was trying to get on a server I'm building with a couple of friends and i tried to move in the game, but the window froze. Then this error screen came up, so i had to exit out of the window. I tried to get back on, but the SAME THING HAPPENED! I just don't know what to do!!! I attached the full report to the bottom so that you can get the maximum amount of information. Need help ASAP!!! THANK YOU!!!! (BTW, the server address is, "192.210.220.131:25565" just in case you needed to know...)
P.S. - It does not affect version 1.5.2. It only affects the Feed the Beast 1.4.7 version
