Hello Sky035
We apologize for the inconvenience caused, as per the description above, you are not able to use the Adobe ExportPDF service for which you have paid, Is that correct?
The record shows that you are subscribed to an active subscription to Adobe ExportPDF on your current Adobe ID. Please use the service through the URL https://cloud.acrobat.com/exportpdf with your Adobe ID and password on a different browser like Chrome or Firefox, or Safari.
You may also use the free desktop version of Adobe Reader to use the service of Adobe ExportPDF, just sign in with your current Adobe ID and password in Adobe Reader, if you need to download and install the Reader, use the URL Adobe - Adobe Acrobat Reader DC Distribution
For more troubleshooting, you may refer to Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Let us know how it goes.
Regards,
Anand Sri.
