I have been able to download the Simple Template code on to the cRIO and was able to make a motor run and everything, but when I went to take that code off and put on gyroscope code it would not allow me to undeploy it and WindRiver said "unable to delete UserProgram from the robot". Any new code that I try to download to the cRIO is ignored. What do I do?

Also, how do you print a variable value to the terminal window (for testing purposes) in the C++? Is it with the "PrintF" function? Thank you very much.
