Retrieving keys from PSSH

[hopelesskeyfinder]

Hello

I have downloaded a widevine protected file and had used wvgnext to try and retrieve keys to decrypt it but cannot seem to find an appropriate key that will work for my file.

The information for the file that i have is:

PSSH: <cencssh>AAAAwnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAKISEO pwO5eDzEMqu574hd6RCWUSEAHoMrj+x0d/utOFN00nuUkSEMQr3Er7d068riqJfcp5OXcSEESHe0uY2kaQpd GrmSAoniUSEMWYIKIR50kEtOMyL7e5yf4SEAztmv69E0R4hbDX 5ifcDF4SELQpaT/H5EEgiB+XsWm2xm4SEGMKnXZmhkBCiu2RZ3QSnLoiED9qgm2gp ES2nQ8fEqZ14n0=<cencssh>

KID:
cenc:default_KID="630a9d76-6686-4042-8aed-916774129cba"

I managed to get a long code from wvgnext but I think it is for on of the introductory videos.

This didn't seem to work decrypting the main file. Is there a way for me to decrypt the file from the information that I have or am i just out of luck with it. Thank you for any help.

The video is offline now I think i missed it. Eventually I will figure out how to add headers correctly...
