Hello thejvtb
We apologize for the inconvenience caused, as per the description above, you are getting a resubscribe page when you are trying to edit a PDF file, Is that correct?
The record shows that you have an active subscription to Adobe PDFPack on your current Adobe ID. With Adobe PDFPack services you can easily create, combine, sign, and send PDF files online. You can also convert PDF files into editable Word or Excel files.
But you cannot edit PDF files with Adobe PDFPack. You need Acrobat DC to edit PDF files. See Adobe Acrobat Pro DC: PDF converter, convert PDFs from anywhere.
If you want to use the services of Adobe PDFPack, you can use it through the URL https://cloud.acrobat.com/convertpdf with your Adobe ID and password on a browser like Chrome, or Firefox, or Safari.
You can also use the free desktop version of Adobe Reader to use the services of Adobe PDFPack. Note: You cannot Eidt PDF files using the free desktop version of Adobe Reader.
For troubleshooting, you may refer to Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Feel free to update this discussion in case you need further assistance.
