professinal development board problems

Using a pro dev board to program a BS1. The target program was for astepper motor. As a test run it should lite 4 led's in sequence. but only pin 0 drives a led. Did a simple test program that should drive only LED #4 (simpley HIGH PIN3) on pin 3, but only pin 0 is driven high. Used a differnt BS1 thinking the stamp might be dammaged, same results. If i make all 4 pins high (PIN0 - PIN3) PIN0 AND PIN1 will drive, sometimes.

Thought it might be a problem using the USB for uploading, but can't get the serial port to recognise the board. Possibly bad cable, will test annother.

Downloaded new Stamp software (went from ver 2.3.9 to 2.4) but no change.

Any help greatly appreaciated

    Could you attach your code and include a drawing of your circuit? It would help.
