Microsoft Office 97

I have a 400 Mhz, 128 MB RAM computer. At first I only had a 7 GB harddrive. I got a good deal on a 30GB harddrive and installed it with no problem. About a motnth later I decided to sell my computer. I moved all the data that I wanted to save tomy 30GB harddrive, and formated the 7GB harddrive which contained windows. I moved Microsoft Office from the smaller HD to the bigger HD. I reloaded Windows98se without a hitch. I installed all my drivers and everything is working. Now is where my problem comes in with Office 97. When I start Microsoft Word, I get the folowing error message; "The Windodows registry has reported that one or more required files are damaged or missing. To correct this problem, run the Word Setup program." Ican press OK on the message and it will let me into word and I can enter text. The only thing is that the spell check or grammer check will not work. The easiest thing to do would be reinstall office, right? The only problem is that when I boughtthe computer it was already installed on the ocmputer, and I did not get an Office disk to reinstall. Anyone have any suggestions? Anything you have would be greatful.
