Robbyjo, thank you for stepping in to help!
NaTSaNoVA , Robbyjo is right, it is easy to retrieve!
All BrillKids purchases and licenses are stored in your personal account, so if at anytime unexpected happened you can easily retrieve your programs and licenses simply by logging in. Then going to your Account and opening the purchases page
http://www.brillkids.com/user/acct-mgmt-purchases.php/Little-Reader-Software.php There you will have every program you ever bought from BrillKids, all your licenses, as well as listed activation slots for every license ( and you can manage those!)
It is also where you need to go to upgrade the program, if you do not have the latest version.
Let us know if you have any more questions
