Unfortunately, you are S.O.L.

Hopefully you don't have too many discs to re-enter or you have another source of data that you could use to import into SNL.

FYI, I lost my configuration recently in doing some testing for an upcoming release. Very fortunate for me, the week before, I had exported my Lists in XML format to a file on another hard drive. I had my backup. Sounds like you were less fortunate.
