Razer Blackwidow keys don't work as they should.

So I bought a Razer Blackwidow (because I spilled milk on my last keyboard) and for some reason on the nordic layout, holding alt gr and pressing the button that makes a ´ should make a \\ but it doesn't. For some reason. Going into the keyboard settings to rebind what the software thinks is the button for the equal sign but really is the one for the backslash, and holding alt gr and pressing ´ doesn't make it do a backslash. Why is this? Is there a fix? The equals sign is shift + 0 on Swedish keyboards. Please remedy this.
