I recently downloaded the free version of Adobe Acrobat Reader 5.0     When I downloaded the program I was able to edit Adobe Acrobat files I got off the Internet.  Now I don't seem to be able to do it.   When looking at the file in question and I click on "File" and then then "Document Security," I see the following: Security Method:  None User Password:  No Master Password:  No Printing: Fully Allowed Changing the Document:  Allowed Content Copying or Extraction:  Allowed Authoring Comments and Form Fields:  Allowed Form Field Fill-In or Signing:  Allowed Content Accessibility Enabled:  Allowed Document Assembly:  Allowed Encryption Level:   

(there's just a blank space after "Encryption Level:") 

So, I think I should be to get into the Adobe Acrobat document and add parenthetical phrases and the like.  It's 60 pages long, so I don't want to print it out or transfer it to Microsoft Word.  Besides, I could make changes in Adobe Acrobat documents when I first downloaded the program, so I should be able to do it now. 

I'll really appreciate any advice anyone can give me.  PLEASE send a copy of your response directly to me at  dreyfuss@ucla.edu 

Thank you very much.    John Dreyfuss    dreyfuss@ucla.edu
