Hello Yolandam,
As correctly mentioned by Aandi Inston that freeware Adobe Reader does allow to organize PDF pages. I have checked the records with your current Adobe ID(email) used to log-in on Adobe forums and found that you were subscribed to Adobe ExportPDF services which are canceled and inactive and the Adobe ExportPDF online service can be used with the freeware Adobe Reader, however, the Organize PDF pages are not included in this service.
I have also checked the susbcription details and there isn't any license/subscription/volume license associated with your current Adobe ID.
With Adobe ExportPDF service, you can turn PDF files into editable Word, Excel, and RTF (rich text format) documents, but cannot organize pages.
If you wish to organize PDF pages and use other services, you may subscribe to Acrobat Pro DC subscription. For detailed information, you may refer to Answers to some of the most frequently asked questions about Acrobat DC
For plan and pricing, you may refer to Plans and pricing | Adobe Acrobat DC
If you have installed Acrobat, you may remove it using Acrobat cleaner tool Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Then, you can install Adobe Reader from Adobe - Adobe Acrobat Reader DC Distribution
Adobe Reader can be used to print, annotated, view and sign a PDF file. For detailed info, you may refer to Adobe Acrobat Reader DC FAQs
Feel free to update this discussion for any further assistance.
Thanks,
Anand Sri.
