You have a 'G' drive? Sounds like a job for Jabo..............
Edit...er, would it be possible to move either Steam to G or Cliffs to C? Whatever you do I think the game and Steam should be on the same path, as CLoD online needs Steam to be running.
If memory servers me correctly, doesn't Steam retain your settings anyway? If not, well good thing you've still got the SoftClub stuff in my documents.
