Here all went fine I guess.
One thing only, not sure does it matter though:
On the 1st pic as you can see, for D2game.dll Date modified is different in restore folder, though it is the same file without any change on it.

I also have Itemdesc.dll set as hidden and date doesn't change.
I also tested with letters

For CRC I guess I can use winrar:
