Assuming you had previously been running version 102 ... Supernova is not yet an upgrade to version 102. Supernova is a beta program. 1. Your old version 102 should still be on your computer and also its data, if you installed Supernova using the default process. 2. To bring in your version 102 data, in Supernova do Tools > Import > pick a profile, typically default-release will be in the name. From there you can bring in entire accounts from version 102, or just parts of version 102 like address book. Please post to let us know whether this helps.
