Just bought the LABX-1 Board, PicBasic Pro and Melabs U2
Using a 16F877a
Here is my program

clear
adcon1 = 7
mainloop:
high portd.0
Pause 500
low portd.0
pause 500
goto mainloop
end

The compiler says that it is compiled successfully and then it loads into the X-1 without error, but it won't run! Nothing happens when I load it into the board/chip. Yes, I have checked to be sure that the polarity of the led bar graph and the JP2 jumper are correct. I have even tried it using low portd.0 just for giggles, and that doesn't work either. I've tested the programmer and the board/chip using the board test program (in hex) supplied with the programmer and it runs fine, making the leds blink, lcd display, etc.

I've read and reread the book but can't find what I'm doing wrong. Sorry to come with such a basic question. My head hurts from banging it in the wall.
Thanks
