mircosoft word files are there but blank?

I have tried to do a system restore using several different restore points, but it always says "incomplete data installation" or something to that effect. Anyhow the files is still there by it's file name, but contains no data. Any help retrieving these documents is greatly appreciated!
Thanks, Texastracker
