Scratched office 2003 instal disc won't read

Hi
I have a Microsoft office instal disc and the associated product key. Unfortunately the disc has been scratched and won't read. is there anyway to get new copy off the software eg a dowwnload from Microsoft? I have a genuine key so it's nothing dodgy!
Thanks in advance

I had this problem recently. A call to MS support and a fee for the media and I had the replacement in about 3/4 days. I suspect you can no longer download Office 2003.
