I have lost the ability to log in to my container.
I have created it with default sha-512 AES encryption, have used it for over 9 months without problems, but recently wanted to make a backup and all went to hell.

I cannot log in into it, always returns:
Operation filed due to one or more of the following:
-Incorrect password.
-Incorrect Volume PIM number.
-Incorrect PRF (hash)
-Not a valid volume

Source: MountVolume:8299

Is there a way for me to check the file integrity ? i've tried restoring volume header from the backup embedded in the volume... doesnt go past password stage :(

What can do in this stituation ? im 100% positive the password is correct
