Thank you for the reply Nagisawa,

As the error would suggest, you seem to be unable to complete the version check. This usually stems from a connection issue but it may be caused by something else with your PC.

First, make sure you are running the game as administrator and that your anti-virus/firewall has an exception for the game. The boot files for the game are stored in the 'My Documents' folder, make sure they are there under 'My Games.' Additionally, it will help if the game is installed on the same drive as the operating system (Drive C usually).

Also try resetting your router and making sure you have no other programs/overlays running in the background (even if you don't think they will affect anything).

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
