If you think you've got some super-awesome-ultra Key Map or Mapped Key that you'd want to keep then you should back up your old profile (just name it something else) and then start fresh because I'm willing to bet that most of whatever you had before is now built right into what the Wizard sets up in a more elegant way.

You don't mention what game, but I'll assume WoW, so I'll link the Quick Start Guide where there are setup videos:

If you're not playing WoW, then the other game-specific walkthroughs are in the upper-right.
