Office Professional 2003 Lost Disc Have Serial Code Microsoft Office 2003 Pro?

Microsoft office 2003 pro? - office professional 2003 lost disc have serial code

I have Microsoft Office 2003 Professional, but someone has the 1 CD lost. I have the code and every 2nd and the disc can not install without the first one. What can I do because I really, I do not want to go and a few hundred dollars, epic spending in 2007, which I do not need. Is there a way to download from Microsoft and in my key to start it. I want it all legal, no download version online cracked.
