The launcher won't launch.

[MrPersonson]

The game has worked fine for the last week, but now every time I try to open the launcher, a window pops up that says "Unable to complete version check. [30605][20448][10009][10019]" I'm not sure if something is wrong with my computer or if it is the game itself. I've re-downloaded the game and it still does this. Also I can't get onto the square-enix website from the computer I have the game on and this is the only game I have that is giving me this problem. If anyone has an idea of whats going on please tell me, thanks for any help.
