Cannot locate Beats audio program after Windows 8.1 Update

Hi All -

I cannot locate my beats audo program (setting, etc) after upgrading to Windows 8.1. I have uninstalled and reinstalled varioud driver types. I'm currently using IDT Audio driver 1.0.6491.0. WHen searching for beats, I get nothing... :(

The Hotkey Fn+B seems to work with audio enhancements, but I cannot locate the program.

Any help on which drivers to try and/or how to access the program is appreciated.
