Games purchased via steam install into the directory Steam>Steamapps>common>(Game Name)
By going to this directory YOU CAN launch the game via the updater if steam will not launch it.
I was planning on posting for help in reference to the updater. It would checksum then attempt to verify image then go back to checksumming then it would stop with nothing to read on the updater status. Left the updater running for a bit and now its fixing some files. Go figure.
