What does this error even mean?

After hours, and hours of endless updating, I launch the game to find this error popping up everytime. I'm really sick of all the headaches this big update has been causing me... Does anyone know what this means and how to resolve it?

Files have been modified.

Using English patch? Use the right one (Sep 12th ONRY).

Fix it first by clicking third button down in launcher to check/repair all files before doing anything else.

Ah, thank you. I had been using the outdated patch.
