What should I do?
There is nothing you can do with Reader. I'm not sure what the other products you mentioned are. They don't sound like Adobe products? But you'll want to ask in a forum for one of them.
Creating PDF and Export PDF are both Adobe products. An Adobe support rep told me I could edit to move page numbers if I purchased Export PDF. But I think I wasted my money by following his mis-advice. And trying to get a live person even in a real time instant message conversation with Adobe is an impossible maze to navigate. Seems like a racket to have you keep purchasing more products and services to do a task that should be so basic and standard.
Create PDF and Export pdf are services provided via the www.acrobat.com website. If you look at that website non of those products indicate that you can edit pdf file. Create PDF does exactly that. Export PDF exports from pdf to other formats, none of those products allow for editing pdf file. If you want help using the Acrobat.com products please post here: http://forums.adobe.com/community/acrobatdotcom
However, I believe if you want to edit pdf files (a very bad idea), then you need to use Acrobat Pro or Acrobat Standard. They allow very limited editing of pdf files.
