I purchased this product first and then read the reviews on Amazon. I decided to continue on with the installation procedure against my better judgement. This is what happened.1. One day after installation my computer started rebooting unexpectly and displaying a messsage from windows. 2. Next, I couldn't get into any of my programs.3. Best Buy said that Windows was damaged and I had to reinstall. Good thing I had my files backed up online...Nope. The back up didn't take...although I was given the green light by the program.4. The tech tried but he only could reinstall the program back onto my computer...Hip hip Hooray...I only lost my children's photos, my lesson plans, and all the info I has stored for my church...but at least I still have the program that wiped out my hard labor.
