Character Problem

[XaLoR]

I recently compilied my own core, set it up etc.
It said there were no errors on completion, which is usally good. :P

Well, I go to log-in, it works, I then start to create a character, the second I click "Create" it disconects me.

Now, if theres an account with a Pre-made character, I log-in, and login to the World. Once it reaches the end it goes back to the Character selection screen and says "Login Failed"

What is the problem and how do I correct it?

Thanks
