Need a program to change the option my mouse does

[NEED WOW NOW]

I got a new mouse for Christmas and I noticed that the two zoom buttons didn't really work.

So I put the CD with SetPoint and looked at the options that I could change it to and I didn't find what I wanted. What I want is to change those two buttons so they increase or decrease the speed when ever I want.

So the question is, Is there a program that allows you to do that?

Heres my mouse:

The two buttons I want to change are the two above where the thumb would go.

Thanks

In my setpoint that I got with my keyboard/mouse set, I can change what any of the buttons do, on my mouse and keyboard. You sure it's not in there?

PS, don't game with setpoint on. Everytime I would press the middle mouse to throw a nade, i would minimize to windows :/

Microsoft Mouse software works great.. im not sure if it support s ur mouse (b/c its logitech) but its worth a try.. and u get a boat load of options.
