function keys are messed up

hi i have a problem with my function keys
i have a razer ultimate 2013 keyboard for my imac(2009)
with osx maverick

and it seems that my f1-f10 have no function anymore what so ever not with fn or nothing
but f11 now functions as f3 and i have f13 and f14 working as f1 and f2

so i tried deleting and reinstalling my drivers for the keyboard no luck it still persists

can you help please?
