maybe its encrypted with another type of encryption, maybe smarcrypt or others.

to decrypt these files only with the program, or people here on forum, or mxc discord who do it paying

How to decect encryption?
I can watch it on hex so what..
if its SmartCrypt, i need patched smartguard l2.exe for inject to decrypted data cos i cant inject in protected exe
or help me to debug protected exe for find encrypted data in memory and copy it
someone can help?
