Query: Expired software?

I was looking forward to diving into the tutorial but was delayed in finding the appliction which had been tucked inside another folder. Upon opening the application I was confronted by the message "This software expired on 12/01/99. Please contact auto-des-sys or your local dealer/contact to renew your software or become a licensed member". I was unable to contact auto-des-sys via the web since I do not have a registered product. I'm confused now about how to go about obtaining current software. Do I contact Amazon, Mc Graw Hill, auto-des-sys or the author? Not a good start to what appears to be a fine tutorial system.
