No sure what was wrong. Maybe a solderless connection was not tight.

Got a couple warning windows about voltage must be 4.5v.
Strange since the power is coming from my PC via the USB port. Then that went away. Got a couple of red "Code Protect" statements. Had to restart the application to get ride of them.

Twice in a row it loaded my .hex file successfully. Good!! Now to adding sonars, SN7404 and the DPDT relay.

Thanks for the support. It really helps!
