Master Lock Speed Dial Problem - Help? - resetting an opened master lock

I went to Staples and bought a new lock to Master Lock Speed Dial, and took him home. I looked to see the video lessons masterlockitup.com that not open the lock. Is there any idea? We have never reset the combination, and not unlock with up, down, left, right, and not say who came up with a different combination.
