Hi Robertom,
As mentioned above, Adobe PDF pack but creating a pdf file the system go to "Pricing/PDF pack for the purchase of the program.
I assume you are working on Adobe Acrobat DC? Or either you are Signing In using a different email than the one used to purchased the subscription.
However, you should download Adobe Acrobat Reader DC and signed in using the correct email address.
1-PDF Pack is an online service that you can use online via: https://cloud.acrobat.com/exportpdf
2- You can also use the services through free desktop version of Adobe Acrobat Reader DC: Adobe Acrobat Reader DC Install for all versions
3- “Sign In” using the email (Adobe ID) under which you have subscription registered.
4- For detailed description of how to use the PDF Pack service, you may refer to- How to Use Adobe PDF Pack
You may refer to the following link for any troubleshooting: Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Let us know if it still doesn't work.
Regards,
Akanchha
