Barrettscv asks the right question.
It's possible that your bindings need to be adjusted. With most all binding models, this is a minor matter of checking a forward-pressure indicator and turning a screw.
It's quite unlikely that your bindings need to be remounted.
If you don't know how to do this with your bindings you can either: (i) rely on the advice of someone here, which (of course) requires knowing what kind of bindings you have or (ii) take them to a shop. If you take them to a shop, they'll probably do a release check as well, which I wouldn't consider necessary, but it's not a bad thing either.
