Can not use my paid acrobat

Acrobat Reader is the free PDF application from Adobe. With Reader, you can do such things as open PDFs, do basic Comments, fill in forms and do a "Save as..." to preserve your answers.

If you want to be able to Edit, Create, etc., you'll need to upgrade to a paid version. If you're on a PC, you can purchase either Acrobat Standard or Acrobat Po. If you're on a Mac, the only option is Acrobat Pro.

I hope that helps.
