I’m sad

Keystaion 49es keys are not working

I just bought a new Keystation 49es. I'm running Windows 7 sp1. I've tried several programs from Mixcraft, EZdrummer, and even Ableton live, but all I get is the first and last keys, on the keyboard, to work. The sustain pedal works too, but nothing else. Device Manager says drivers are up to date.
Any help would be appreciated.
