Hello Tims,
We apologize for the inconvenience caused, as per the description above, you are not able to access the link to use Adobe ExportPDF service, is that correct?
The record shows that you have an active subscription to Adobe ExportPDF on your current Adobe ID, access the service through the URL https://cloud.acrobat.com/exportpdf with your Adobe ID and password on a browser like Chrome, or Firefox, or Safari.
You can also use the freeware Adobe Reader DC to access the service of Adobe ExportPDF, just sign-in with your current Adobe ID and password in Adobe Reader DC.
To download Adobe Reader DC use the URL Adobe - Adobe Acrobat Reader DC Distribution
For troubleshooting, you can refer to Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Let us know how it goes and share your findings.
Regards,
Anand Sri.
