You are referencing a client class on the server. Maybe use proxies or different methods to get around this problem. We can't help you any further without the crashing code though...

 

There could also be a problem with your forge installation though, since there is no reference to your code in the log.

You have to create and use proxies for your code to work. The cool thing is its universal so you just code it once and it works both ways. Follow this http://www.minecraftforge.net/wiki/Tutorials/Basic_Modding
