Hello CarriePS
We apologize for the inconvenience caused, as per the description above, you are getting Conversion Failure error while exporting a PDF file, Is that correct?
The record shows that you are subscribed to Adobe ExportPDF service on your current Adobe ID.
Note: Adobe Acrobat Reader DC is a freeware software and there is no paid version of Adobe Reader DC.
I have checked your records with your current Adobe ID, and you are only subscribed to Adobe ExportPDF service.
Try exporting the PDF file through the URL https://cloud.acrobat.com/exportpdf with your Adobe ID and password on a browser like Chrome, or Firefox, or Safari and see if this brings any difference.
For Adobe Reader DC, please sign out and sign back on with your current Adobe ID, and check for any pending updates of Adobe Reader, install the updates and reboot the machine. Try exporting the PDF file.
You can use Acrobat cleaner tool to remove Adobe Reader Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Reboot the machine and install Adobe Reader from Adobe - Adobe Acrobat Reader DC Distribution
For conversion failure error message, please refer to the following KB article File conversion error | ExportPDF
You may also 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.
