For one, I believe the demo for CE checks to see if you've turned the clocked back, and won't work if you have. I could be wrong about that though.
Right you are, the HC demo doesn't appreciate seeing files with dates newer than the system time. The good news is that if you are legitimately setting the clock back there isn't a problem... You just set your clock to the real time, then fire up the HC demo.
