I can't upload new books and get error message on newly installed 4'5

This forum is to discuss how the forums work, not individual programs

Provide the name of the program you are using so a Moderator may move this message to the correct program forum

This Cloud forum is not about help with program problems... a program would be Photoshop or Lighroom or Muse or ???

I think it has something to do with the permission to the PC from Adobe. I can't change the authorisation because I don't recall doing it on this version. Now of course I can't do a thing Adobe have passed the buck and put me onto the forum for help so I hope someone out there in the ether can help I need these books to read when I am laid up after my operation.@
