RichEdit line insertion error

[Tapdancin_Jeebus]

Okay,
When i press start for graal, and it's loading the servers, it loads the servers but then it pops up this 'RichEdit Line insertion Error' What is this?

I can do quests and my graal works fine, except, I can get messages, yet I can't message back and the error window pops up when I try to message back. Also when I try to look at people's profiles, the window pops up. Does anybody have a clue what this is? And if you do, how can I get rid of it?
