If it's a trial package, merely un-install it and forget it. Trial
software is usually programmed to stop working after X number of activations
or when some delta number of days have passed, or some other trigger. I
trust you didn't pay anything for this "trial" version (if you did, I have
some land I want you to look at) so just walk away.
