Hello rolfg80329474
As per the description above, you are not able to use the Adobe PDFPack services, Is that correct?
The record shows that you have an active subscription of Adobe PDFpack on your current Adobe ID. You may use the services through the URL https://cloud.acrobat.com/convertpdf with your Adobe ID and password.
If you are using the free desktop version of Adobe Reader, then sign out and sign back once with your Adobe ID and password and check for any pending updates of Reader from Help Menu>Check for updates.
For more troubleshooting, you can refer to Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
To download Reader Adobe - Adobe Acrobat Reader DC Distribution
Hope this helps, and let us know how it goes.
Regards,
Anand Sri.
