I bought PDF Architect Edit but could not insert pages into a document. I was prompted to buy PDF Architect Standard which I did, installed the different modules, still cannot Insert pages. When I try to Activate, I end up on the Buy page.
I guess you're using PDF Architect 6, correct?
First things first: The insert feature is not included in the Edit license. The Standard Package is the correct license.
Kindly see if you're able to activate your Standard license this way: https://support.pdfarchitect.org/customer/en/portal/articles/2936787-how-to-activate-pdf-architect-
If that's working, contact our PDF Architect support team and ask them to refund your edit module: https://support.pdfarchitect.org/customer/portal/emails/new
