Can anyone help, Adobe does not seem to have as much info on their site as I need. I have Acrobat Sdt 6 and want to upgrade to a Prof version. Professionl 6 would be fine but I see a product listed on some sites as an upgrade to Prof 7. It is cheaper than the Prof 6, what I need to know for sure is if it will update my Std 6 to the Prof 7.
