Driver station not detecting robot code

[2544HCRC]

I'm in the same boat. Following the "benchtop test" procedures in the control system manual. I have updated labview. I have imaged the cRIO. I am uploading v19. I have opened a new program, gone through the steps and uploaded the program "main.vi", all seems to go well. Nothing then seems to happen. The book says I should be able to control the robot, but nothing is happening. I log out of the developer window and into the driver station window. I have a connection (green light), no errors in the diagnostics window, but I have a "no code" in the lower left hand window. I have about wore out the text on the manual pages I've read them so many times. I'm brand new to this so I'm assuming the problem is somewhere between the chair and the computer, but for the life of me I have no idea what. BTW, all other tests to this point seem to be ok, blinky lights are all blinking in the correct way.
