all of a sudden I am unable to copy/paste using ctrl+v & ctrl+c from Adobe PdF documents to another document. PLEASE HELP!!!

Me too.  Recently I can't do a Ctrl+C and Ctrl+v, or Ctrl+x and Ctrl+v. It was working.  I might be able to do it once when I open the pdf.  Very strange.  I can do right click for cut and paste, but that is a little slower.

You also have Acrobat XI? Because that's a very old version, not compatible with any current OS (which doesn't mean it won't run, just that problems are to be expected).

Did you try restarting Acrobat?
