Let me try and clearly understand. Have you actually downloaded the game already and you just can't get the game to load? Or is it just not letting you download the game onto your computer at all?

Also, I noticed you changed your "Display name" to Shade. There is a glitch where it sometimes wont let you reply to messages/blogs while it is changed. If you have trouble with replying to posts just clear your display name.

Are you downloading from the official page?
