Unable to get past character select screen

[OrionOmega]

SO, for the past day now, every time i try to log in, i get all the way to the character select screen, i pick my toon, and hit play. and nothing happens after that. my screen will freeze, and i will not progress past that point. im still able to move my mouse. and most times it will go to the black screen and say either "youve been disconnected" or something about the server not responding. any idea how i can fix this, or what might be the underlying problem?? thanks!
