Just as an update for anyone else who encounters this issue, I contacted Customer Support and was told that I did purchase the full version.
If anyone would like to compare notes, I bought this Creator 2009 product by clicking on an "upgrade to Creator 2009" link in my old pre-installed Creator DE program. (I know it's a separate product not an "upgrade," but that's what they called it.)
After clicking the link, the product page on the Roxio website offered me Creator 2009 for $69.99 "after $30 instant rebate". The page also said "Save $30." Since $99.99 is the full price for the full version, I had no reason to doubt that I was buying the full version.
My receipt, however, says Creator 2009 - ESD (OEM).
Nevertheless, as I said, Customer Service says this is the full version.
I decided on a refund since tech support (whom I also contacted) could not offer any solution except a link to the User Manual.
I liked the product in general. Customer Service was friendly and responsive. I would buy Creator 2009 again if Roxio could resolve my issue.
