Homebrew Question Can't extract NCA file from .nca folder

[Real.96]

I'm trying to extract a nca update file from a .nca folder with a single 00 file inside. I downloaded last hactool.exe release and used this command:

hactool -k foldername/prod.keys -t nax0 --sdseed=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX --sdpath="/foldername/folder.nca" --plaintext=game.nca "D:/foldername/folder.nca/00"

prod.keys file is inside the correct folder, i extracted it using Lockpick_RCM. I'm getting this (i removed the values between the ""):

[WARN] prod.keys does not exist.

Done!

What is the problem?

I'm having the same issue with Crysis.
