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

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
