That is the error I get when trying to install the game once I sign into the launcher. It will begin downloading and all of a sudden it will stop and that is when I get the error. I have tried every method that has been suggested by Square-Enix, such as disable startup programs, antivirus, try different browsers, forward ports, upgrade firmware on router, reset router, start in admin. mode I even tried safe mode with networking. I have windows 7 and bought the digital download CE copy of the game.

I am at a loss which is why I am now posting here. I must also add that when I get this error it knocks my entire network offline. Once I close out the program my network comes back up. I have tried various other online games and this is the only one that causes my network to crash.
