Ok, I bought the merc stealth from Steelseries on sale and I got it today, it works great in game but I decided I wanted to set some of the keys I have to have the control panel to change and so I downloaded the control panel, and it still refuses to let me fix the keys like I'm supposed to be able to.
It won't even let me set them to open WoW.
The keys I am talking about are the keys that are roman numerals at the top of the keyboard, the 'I' 'II' 'III' keys
Does anyone have a merc stealth and know how to resolve this issue?

I looked through the FAQ that comes with the control panel and none of it works and everytime I try to load their support page it says the page doesn't exist regardless what computer I try from.
