Non responsive buttons
 

Ok so new issue, got the window resized, and mouse look wasn't working so I went into mouse options and adjusted it. Now I can get to login screen but none of the buttons such as, "enter world" work. the appear to press down, but nothing happens. As it stands I can see the toon I created, just cant enter the world.

Are you playing in full screen mode?

Have you tried navigating into the game using the keyboard? At character select I think you just need to hit enter. Won't fix your problem but could be a way in until you do get it fixed if the game plays normally once you're in.

Possibly have it in full screen with the resolution set to small under options at login screen?
