Failed to connect to the target.

[ATEC Robotics]

Hello, we are a second year team needing some assistance. When trying to deploy a new program onto our cRIO from labview we keep getting the same error message "Failed to connect to target." I dont understand what this error is. We have encountered a "Failed to connect to real time target" and fixed that problem. How we start to get the program on is 1.) Build all. 2.) Build again from the properties window. 3.) Deploy from FRC Boot-up. 4.) Then Run as Startup. Please respond with any useful tips or suggestions to get us back on track.
