Very frustrated with Acrobat XI. I use a database that contains scans of old files. when i try to save these pdf files from the Safari browser then re-open them with Acrobat XI, all I get is a dilaog box saying that cannot be opened and to save them by using the save button from the Print dialog box. When I try that method all that is saved is 2 blank pages.
You get them when you get Acrobat (which you got).
Some articles that may help:
Try with a different browser?
