Two finger secondary click not working!

I have a 15" Macbook Pro with Retina. Brand new as of December 2012-

I have searched everywhere for a solution to this! I have solved the problem only for a few minutes at a time by entering a short script into terminal, but nothing has worked permanently. I can get the secondary two finger TAP to work, but I can't seem to make the click to work... And yes, the option is set to work.

When I log in as a guest, the feature does work, which seems to indicate that the problem is confined to my user account. Can anyone help? I would appreciate anything!
