Hi,
I don't know, perhaps I'm way late here but your original program reads HIGH 0 and LOW 0 which may work on a BASICStamp but I don't think it works with PBP - even after including the BS1/2 defs - which you don't seem to have done anyway.

Al, covered it in his program by changing the code to HIGH PORTB.0 etc but then in a later message you say you're using PORTB.4 instead. Did you change the code so it reads HIGH PORTB.4 etc?
