Query: Don't buy if you have earlier version

I had to purchase the 2007 upgrade when I bought my new computer and could not find the disk for my earlier version of Office Professional. They have changed it so much to look like adobe that I spend more time trying to do simple task as center a column in Excel than working on the project. If I ever find the disk for the last version I will reload it into my new computer.
