Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

[Nezarn]

I can't run this game. What should I do? Is the ganme data corrupt?

If you just copy the disc game to dev_hdd0 it won't work, you need to either install it by booting with the boot game option (while you don't have the game files in dev_hdd0), or if you don't want to have the game 2x on your hdd (since its quite big), install it manually.

For me this is how the game's folder looks like (with manual install)
