Volume control on new Wired keyboard?

Hello! I use to have the old short wired keyboard but my cat spilt water on it and half they keys stopped working so we finally got a new one.

When I plugged it in I noticed IMMEDIANTLY the F keys at the top were off and not in the right place, I was able to fix most through System Preferences> Keyboard and mouse< keyboard and changing the hot keys to the right onces BUT I could not figure out how to fix F7-F12 as the volume controls

I looked at many other questions simular and I know one said hey download from http://support.apple.com/downloads/#Keyboard%20update But none of those worked they said can't find your keyboard! and I know someone said try using a program named Spark but after I made the new hotkeys they like.. They didn't work either...

Does anyone know how to fix this? It's a keyboard with numeric keypad and wired NOT wireless.
