Error starting up. "Final Fantasy has stopped working.."

[Lissea]

It Said that the update is not applicable on my system.

I've found on a forum to delete the folder in %username%\My Documents\My Games\FFfolder. I've delete it completly but it change nothing

But the most weird thing is that when I copy (Not move) the folder "FINAL FANTASY XIV - A Realm Reborn" on another new folder with a new another name it's working fine. But when I close the game and try to relaunch it it's over. I need to do again the new copy.

My C drive is a Crucial SSD MX500
M D Drive is a 1TB Seagate 7200 T/M

I'm not sure but it's since the patch 2.4.
Quick other important precisions :

1- The folder Name Cannot be the same. I must create a new folder Name and put the FF Folder in it. and it's works.
2- I precise again that all others game are working perfectly and I have 10 installed.
3- I precise that I use " Driver Genius 14" to update all my Drivers .
4- All Windows Updates are installed
5- When an update is pushed like this morning , the game is launching fine once. But once I quit and try to relaunch it's over.
6- I've check my directx9 Version with the official installer http://www.microsoft.com/fr-fr/downl...ils.aspx?id=35

I love this game ! Please Square Enix help!
