Cant change class?!!! WTF

When i chose the new class and want to press play its grayed out WTF

Uhh... you cannot change classes as long as your character is alive.
You can just go kill yourself and make a new character, but class changing on a single char is impossible.

You unlock new classes by geting fame on your current class, the locked classes should say witch class you have to play to unlock the new class.

You gotta get to level 20 on most of the classes man, and thats a challenge itself if you just started the game. Took me like 3 months of constant playing to get level 20 characters consistantly.
