Excel file Macro to protect worksheet and establish trial period.

I have an excel file, which I want to share for a limited time (like a trial period of "x" days). Users should be able to use the excel file until the time is over. When time is over it should say that trial period is over and make the excel file useless. During the period the file is usable, users cannot edit or go into the cells or modify/copy, etc. This has to work even if the users saves the file under a different name. The purpose is that the user tries the file for a time and then comes back to me to buy it.

I searched on the internet and found this site which interprets what I need to be done.
