Try reading this thread:

http://lotrminecraftmod.wikia.com/wiki/Thread:171229

the error message you are getting is the exact same one that you get if you create a custom waypoint. You get booted from the game and then when you try to log back in you get:

"A fatal error has eccured, this connection has terminated"

If you read this thread you will see Mevans already has a fix and is waiting to incorporate other bug fixes before the next release. No need for him to chase down a bug he has already fixed. If I'm wrong and you didn't create a custom waypoint then look at the file fml-client-latest.txt in your logs folder (in the .minecraft directory). Look for any text referring to an error.
