Guild Wars 2

The initial login screen always appears, and it lets me log in, but when I click play the screen turns black and stays that way, no matter how long I wait. I have tried quiting the game, reinstalling, and restarting my computer, but no matter what I do the character choosing page never shows up. The mouse turns to the hand icon but the image of my character never shows up.
I used to never have any problems. then one day it just stopped working.

I have a mac book pro
with a 2.3 GHz intel core i5
with an intel HD graphics 3000
and OSX 10.9.2

what is wrong with the game or my computer, as I said earlier it worked for a couple weeks then my internet turned off while I was playing the game and the game will not open since, it has been like 2 months since it first started. Any Ideas?

After I log into the guild wars 2 game, I click play but the screen always stays black and does not show the game. I have played the game multiple times on this computer so I know the computer can handle the game. Does anyone know why this is happening
