Street Fighter Sterring Wheel with Quick Release

I bought a Street Fighter Quick Release steering wheel assembly from a popular vendor. However, it will not release and separate when the button is depressed. No instructions came with it. Ideas and help please!? Thanks.

It is 1250am where I am right now (Nova Scotia). Just got a note from Chris at Demon where I bought my steering wheel. Problem fixed. Now that is great customer service!!!

I'm not really sure. I gave it a blast of Blaster, and it worked. Or maybe the phase of the moon changed when it worked on my last post midnight try!!!
