    No valid Acrobat serial number found


      Since upgrading to Dreamweaver 5, Acrobat (from CS3) will no longer open documents. I have Windows 7 and have tried following the help instructions (solutions 1,2,3) but then fail to see some items as they are either not there or are greyed out. Please help!
