Server won't work, please help.

[davebth777]

I have a Voltz server that I host and It used to have the recommended version (1.0.11) and I recently upgraded my server and my client to the latest version (1.1.3) and the server works fine, I can see it when I'm in my multiplayer menu, but when I connect to it, my minecraft crashes. The same thing happens to my friends when they try to connect too. Crash report is as follows:

Somebody fixed this for me in another thread, http://forums.technicpack.net/threads/anyone-know-how-to-fix-this.42548/

Apparently it's due to a mekanism update.

"change the config file for mechanism, there is a line near the top that says updatenotification=true, change that to false, save and reload technic."
