Activation Office 2003 Crack I Tried A Used Serial For Office 2003. It Asks Me For An Activation Code Based On It. How Do I Start Over?

I tried a used serial for office 2003. It asks me for an activation code based on it. How do I start over? - activation office 2003 crack

I entered a serial number I found online (foolish, I know). You must then go through the process to try to get an activation code, but it says the number is used. I would like to pay only, and do what is right, but I do not get kicked off the first row. Ideas?
