Yes. Even though I find it easy to decode the files, I would not buy a product that requires decoding unless the merchant states very clearly that if it doesn't work for me, I'll be reimbursed. Reason for that is that I can't be sure the object I have is the exact same version as the one used to encode the files.

An example of that is Victoria 3: how many different versions of that object do we have? I lost count!
But it's not the only one. (A3,M3,V2,Mil "anything", etc.)
