n50 Speedpad Problem

I've got a Nostromo n50 Speedbad by Belkin that I use for gaming but I've always had an issue with it. When I press keys # 3, 6, and 7, it performs the functions of those keys but also the function of key 2. For me, this basicly means if I walk forward and left while crouching I also do something else I don't want to, which usually means I don't bind a command to the key and have less buttons to work with. I am using the driver for the device that I got from Belkin's website. Belkin's website acknowledges the problem, but does not offer a solution. Does anyone know of a way to fix this, a patch or maybe some 3rd-party drivers?

Edit: I couldn't find a fix anywhere, so I just ordered an n52, which apparently doesn't have this problem.
