Latest questions about "jetform design"

After an updated JetForm PDS is copied to production, I get an Adobe Acrobat error: "Acrobat could not open PDF because it is either not a supported file type or because the file has been damaged.

I work with Jetform Output Designer 5.4 and I am facing the problem with one of the drivers. I understand that Jetforms is owned by Adobe now and was also discontinued a few years ago.
