put them back in the hfs folder, and now, when I start Vindictus, it goes to the 'Vindictus' black-background box, and closes.

How do I fix this? Did I possibly edit something incorrectly?

EDIT: I apologize, but I hadn't checked the file names. I see now that '286FE9924483F382029EF68BA6C260B3C2563BF9' is the correct file name for '286FE9924483F382029EF68BA6C260BC2563BF9' , with a one number difference. The game is starting after fixing this. Please, do not respond to this thread with assistance, as it's been fixed.

It might be that you didn't pass the secondary sum check
