Query: Upgrades Not the way to go.

I purchased the old version of Photoshop CS because I had upgraded my computer from the original photoshop 3 with upgrades. After having my computer crash from an automatic upgrade they had to reinstall the operating system. My photoshop upgrade would not work. A big mess.I recommend buying stand alone programs, not upgrades after this. Needless to say I like Photoshop CS.
