Query: dead CD

Beware of faulty CD! I've been a big fan of Topo! for a long time. I have several state CD sets. The software has gradually improved over the years. This single CD of Colorado doesn't work. It installs fine but doesn't see any of the maps on the CD. It was stupid of me to throw out the packaging so I guess I'm screwed :-(
