Fritz 5 requires the CD to be inserted after a certain number of date changes.
Somewhere between 14-20, I don't remember exactly. Each time it is run on a date
different from the last one, it counts down 1. Genius 5 requires the CD to be
inserted after 30 calendar days, or 95 uses, whichever comes first.
