About six years ago I downloaded, registered, and paid for a copy of Generations 8.5.1 from Sierra. It's been a great program and had none of the XP problems discussed here. But, my computer finally died and I need to re-install everything onto a new computer. I have the original downloaded file, but when I run it it demands I pay for the program again with a credit card or call telephone numbers that are no longer functioning before it will install the program. Any e-mail I may have received with registration codes is six years lost in hyperspace. Does anyone know how I can re-install the program and make it work? It wants a registration number.
