Hi
I played without problem with windows 8, some weeks ago I updated to 8.1
Yesterday I bought a subscription and installed the new patch 2.4

The laucher works fine but when I click Play the game doesn't load and gives me this message.
I tried reinstalling it but it didn't work
Drivers and windows are updated FFXIV is the only game that doesn't work.
