When I bought my Dell Computer Dimension 4600, MS Office 2003 came installed.  A little bit ago, I downloaded a trial version of MS Office 2007.  When my trial time expired, MS Office 2007 disappeared as well as my MS Office 2003.  It is no longer on my computer.  I've tried all the installation disks that came with my computer, but none of them have MS Office 2003 on them??? 

 

I must have accidentially deleted my MS Office 2003 when I asked to try the trial version 2007.  How can I get my MS Office 2003 back???

 

Please help!
