Can't save my pdfs to my computer

[PaulT_in_Dallas]

After a hard drive crash and replacement, I recently had to reinstall Acrobat Reader.  Since then, when I try to save a pdf that is received as an email attachment or sent to my computer from my scanner, I get a message that the file is in use, and that the file may be in "Read only" or another user may have it open and to save it under another name.  The "Save" button is inoperable and I am attempting to use the "Save as" function, which has always worked in the pst. 

Any ideas? 

Does Adobe actually have customer support or do we have to rely solely on the Community postings?

Thanks!.

Saving a e-mail attachment doesn't require Acrobat Reader.
