I had office 2003 installed on my computer. It was working fine, but then I decided to restore my computer to the default settings because it was a new year, so obviously everything is gone. Now that I'm putting everything back on it, I have to install Office 2003. This program is very important and it was working fine the problem is though the computer keeps saying that my serial code or the "CD Key" is improper. I would really appreciate it. Its the Microsoft Office Professional Edition 2003; and I really don't want to pay another 100 dollars for a stupid mistake that I made. :ashamed:
