Function Keys No Longer Working

I have a Mac Mini, with Apple's bluetooth keyboard, running Mavericks (OS X Version 10.9.1) and Parallels 9 (Build 9.0.24172). I have two VM's on this computer, Windows 8.1 and Windows Server 2008R2. My function keys used to work and I don't know what the heck happened. They no longer work.

My Mac Keyboard Settings, the "User all F1, F2, etc. keys as standard function keys," is checked. Even pressing the Fn + F-Key does not work. What am I missing?

 

Hi Caaspre,

Check the below KB Article to enable the function keys;

No change. Function Keys still do not work.
