Microsoft Office 2003?

I recently installed my boyfriends copy of microsoft office 2007. Whenever I try to go into things it wants me to activate it. I can't because it has already been installed under that key code too many times. I want to change it back to Microsoft Office 2003 or have it work. Also it says that I can only go in there 19 more times before it will not let me do everything anymore. What do I do?

Microsoft Office 2003?
un install it in add remove programs


2003 should still be there afterwards
Reply:I think you might have to un-install office 2007 1st. Then install office 2003.
Reply:If you have the CD and Key for 2003 your good dis-install 2007 reload 2003 if not get the credit car out your times running
