Surface Type Cover 2 question...

I just got a Type Cover 2 for my Surface Pro. Does anyone know if there are new drivers to be used? My screen brightness keys do nothing (F1 & F2) while F3 to F12 do what they are supposed to. At first, my Backspace wasn't responding well then I realized it was only in Outlook and in the subject line. Weird :-/ I really wanted to wait for a Power Keyboard, but my touch keyboard got too tiring and I had to give up on it. Anyway, any input is appreciated.
