    Serial Number Issues


      Hi -

      I purchased AE CS4 upgrade and received it in the mail today.

      When I try to install it I put the CD in and it asks for the serial number, this is all fine untill it gets to the next screen where it asks for the previous serial number (AE7 professional) when I put this number in it says that it's invalid.


      any ideas?
