JUSTRAGE'S PROFILE

hey i have today a error in RPG Maker XP:
Your system clock appears to have been changed, possibly in an attempt to defeat the security system on this program. Please correct your system clock before trying to run this program again. If your clock is already correct, rebooting the system may fix this problem, otherwise contact the author of this program for instructions (report code CCB-A).
In the internet, I found out that I need a "fix clock key" to fix this. Could someone please send me one?
