That means some other application is using one or more of the GPIO allocated by the HG GPIO program.
Check out your /etc/modules file to see if there's the LIRC driver activated on some GPIO's pin.
Then you can either turn off the LIRC driver, or set to OFF already allocated pins in the HG GPIO program.

Cheers,
