What happened was I ran the update to 3.43. It would not communicate with the programmer or esc. I then tried to use 3.42 and it would not communicate either. I removed 3.43 hoping that would fix 3.42 but it did not. I used another computer with 3.42 and everything is fine there. My next test is to go back to the first computer where I removed all versions of 3 series software and installed 3.42 from a jump drive. I wont get to test that until later today. Just for info the computer having the problem is a XP machine.
