I've also had my step for over 10 years.
I've never noticed any squeaking.
Are you sure it's the step and not the floor (if you have a wood floor)?
You can also try stacking the risers in a different configuration, which may help you find a better 'fit'.
Another thought: are you sure the squeak is the step itself, and not just the rubber on the bottom of your shoes squeaking against the plastic of the step? If that's the case, there's not much of a fix for it.
