Binding button 4 and 5 on the Razer Deathadder

I've been having a terrible time trying to figure out how the mouse buttons on my Razer Deathadder interact with AHK. I did some research over on the AHK website that said Xbutton1,2, etc work usually but it doesn't work at all for me and no one seems to be able to offer any help on their forums.

Any info would be greatly appreciated.

Can you just set those buttons on the mouse to actual keystrokes through the Razer software and then use those keystrokes in AHK?

Good god man, you're a genius.
