    I cannot activate cs 5.5 upgrade from earlier version of indesign.

      I have been using indesign cs5.5 which was an upgrade from an earlier version of indesign which I purchased many years earlier. Problem:  I was using 5.5 happily but last week I had to reformat my hard drive (a nightmare!) and now I am trying to reinstall and use 5.5.  I get an invalid serial number when I put in the earlier version #. I thought my original version was 3.0 and the disc says 3.0 at the bottom, but customer support says it is the original version.  I have the serial number for the orig and the 5.5 upgrade.  Can you please help me install 5.5 again? I need it for business.

      Thank you.
