Post here any questions/suggestions you have about novaPDF SDK or novaPDF OEM.
I replicated the problem with this debug version and took some time to inspect the log file it produced. With it, I was able to determine that our code was not calling LicenseApplication for some report scenarios, specifically these were subreport print jobs that were appended into a single PDF. When I corrected our code, the "unlicensed" errors disappeared, even when quickly restarting our application. So it is resolved. Thank you for your time!
