Macro for clearing parked addresses

Hi etc brain.

 I would like to write a macro that clears out Parked Addresses and restores it to the house park settings.

I have done this with the channels (Park Enter Live 76 Full Park Enter Clr_Command) where 76 is the house lights/aisle lights that I want parked. The first Park Enter clears any channels parked during the show, and the rest restores to the channel I want to be parked.

However, I can't do this with addresses.  From Live, Address Park gives me an error code before I can hit Enter.  I can clear a specific address from live, but not any and all addresses sight unseen.  The manual (1.4) states I should be able to clear all parked addresses by {SK} Address Park Enter.  I get the BEEP right between Park and Enter.

  I'm running  version 1.4.1.

I'm trying this because parked information doesn't re-load or clear with loading a show, so if I re-load a preset room patch after an event, any channels or addresses parked during that event will remain parked.

 Any brilliant Ideas?

Thanks.
