Microsoft Office 2007 uninstall?

I installed the 60 day trial of Microsoft 2007 and I didn't uninstall it, I removed a folder I wasn't supposed to get rid of. Now when I try to re-install it, a message pops up telling me a required file is either missing or corrupted and telling me to run setup again but I keep getting the same message. Any idea what I can do? And by the way system restore does not work for me. I tried shutting Norton off too, nothing. Any help is greatly appreciated.

You probably have to buy the the program becuase you only have a 60 day trial

you may have deleted the file that keeps track of time (just a guess) and they think ur 60 days are over
