Re: I adobe acrobat 7.0 professional. When I open or save a PDF it reverts to Adobe Reader XI. How can I change that to the pro as it has far more editing options.

You may want to keep Reader. You may want to select Acrobat as your default, but be able to click on a PDF (or PDF link) to open in Reader when needed. There are likely some PDFs that will not open correctly in AA 7 because of new features folks add. Just because it opens in Reader XI does not mean it is in the new format, but just that is the default opening you have. To tell the type of file, you have to open the PDF and check the properties (ctrl-D) and check Description>PDF version.
