Disabled extension, can't re-organize pdfs anymore- have a paid subscription via university

[Mriganka5CD5]

Hi, my universstiy grants us access to the paid version of adobe acrobat reader dc. I used the funcion that allows us to reorganize pdfs but i disbaled the extension and now i can't find it or use any of the paid functions- they don't appear in the tools section anymore and no matter what i do i can;t get them back. i tried deleting and re-downloading it but that didn;t work. even if i sign in with my university id, it doesn't change

There is no paid version of Acrobat Reader DC. Is it possible that you were using Acrobat Pro DC, but are now trying to use Acrobat Reader instead? If so you need to install the app that is paid for.
