Ok just got this game thru steam, maybe not the best idea since...well... I play with the arrow keys and numpad when playing FPS, so shoot me. pun intended. Anyway, with L4D2 or pretty much any other FPS I have ever played did not have this problem...that any keys besides the arrows which reside on the "right side" of the keyboard do not work. Bind reload to NUMPAD0, nothing. Bind it to Mouse5, works. Bind sprint to END, nothing. Bind to \, works. Checked settings and sure enough they are still there, saved just fine. But they literally do nothing. Wtf is this!?
