As I have noted on the listing, a number of people have encountered the same problem. The registration process is unsuccessful with a "Invalid or damaged key" message. I need a prompt fix since i acquired the program to put together some photos for a party this weekend. I have yet to receive a response and my initial e-mail note was yesterday at noon. If the problem is related to a virus check performed by our network, I can have the Registration key sent to a personal e-mail address. Please let me know ASAP.
