I downloaded V2 and didn't buy the CD. What happens if we wipe this computer clean (as we're contemplating)? Can I re-download V2 if I have the serial number that I got when I made my purchase? I would make my own CD backup, but I see two folders that both installed today, Scrapbook Max and Scrapbook Max 2; both seem to have about the same items in them. I'm not sure which one I would need to re-install the program.
