Important: The download version of CloneDVD 2 no longer accepts serial numbers (like the one found on the serial card in your retail box). If you want to update a box version of CloneDVD, you need to first exchange your serial number for an online key (this exchange is free of charge).
CloneDVD 2 Key Exchange
Did you buy the boxed edition or the download from Elby edition ?
If I remember correctly this serial exchange was implemented when CloneDVD moved to version 2. If CloneDVD is advising that is will exchange the serial number for the online key automatically then why donâ€™t you allow it to do so?
