Gonzales & Hyperltie Bindings

I just bought the Gonzales 138 pro model wakeboard today and put 2003 Parks bindings on it. I tightened the claw system down tight, but the botton of the binding plate doesn't touch the board. Is this a problem? The bindings are secure but the plate isn't touching the board in the middle(directly under the bindings), but rather on the sides closer to the claws. Also, I used to ride a 140 Premier or the now the ERA. Anything I should know for my first time out on the Gonzales?
