How do I make all copies of a spreadsheet file inoperable?

[Ed]

Hi
I made a game on an Excel spreadsheet that will automatically play one hand
after the other continuously.
I plan to offer a free demo that will automatically stop after playing a
certain number of hands and then will play no more.
This is all working fine.
The problem is, you would be able to reload the original file from the
harddrive and play the same certain number of hands again and again.

Is there a way to have the macro stop hands from being played (on a copy
that is reloaded into Excel from the harddrive) at the same time that play is
originally stopped?
Thankyou
Ed
