I cannot "Save As" all of a sudden and I need this feature to function in my job.
I cannot save my PDF files "Save As" all of a sudden - please advise.
I have checked the Properties and several other things with a colleague and nothing we tried has worked. We even removed the program and reinstalled.
We believe is has something to do with Security as the header shows (SECURED) - Adobe Reader
and the Security Method under the Security Tab for Properties says "Password Security", 
but I don't know how a password could have been added, because I did not do anything different.

Since this is a secured document, the "Save As" button is likely grayed out due to security settings. To see what is restricted, look at the "Document Restrictions Summary" area on the security tab. A password limits what actions a user can perform with the PDF file (anywhere from opening the file to making changes to the file, and thus, no 'save as'). These settings would have to be actively applied by someone, most typically the author, but anyone who has unrestricted access to a file can apply security settings.
