Some weird things happening on my system so I am contemplating a fresh re-install of my Win7 OS. I point to the Task bar and something else loads instead, Freetrack keeps locking up in game, button assignments suddenly stop working, etc. (other than that its fine.....

)
If I delete the current Win7 install from the HD partition (I will back up my various ini files first) can I just re-install CLOD (CE Disc Edition) or do I have to delete it using some Steam Procedure?
