The keyboard is an old Saitek Eclipse, the mouse, which is also not working, is a Razer Lachesis.

I have the same issue. Also when I try to use the keyboard to navigate the menu, the selection jumps three or four places every time I press the down key, the up key doesn't work, neither does backspace and when I do manage to select the right box, I can't type anything into it.
