Query: BUYER BEWARE - BACKUP YOUR COMPUTER FIRST!!!

I started on IBM PCJr's in the mid 1980's, and have built several of my own computers. That being said, this programPhotostory on CD & DVD 5is undoubtedly the worst I've have ever paid money for. After installation, over half of my programs would not work, including Yahoo, iTunes, and Adobe Elements. Booting up, my computer kept popping the error boxes stating many of my programs that were shutting down due to memory violations and missing files. Half of my Start Menu programs were missing, and the links to System Restore were gone. When I forced a System Restore, I was advised that the .dll's were missing. GREAT. After manually deleting the three installed program over several hours, the links to System Restore were restored, but all the restore points had been deleted. This program CD is now a frisbee. I refused to even contact the company for tech support due to the severity of the installation errors. What a nightmare.
