A cRIO can become locked if you abruptly loose connection to it. A library will become locked if it is open in two projects at the same time. (Remedy = closing all but the desired project. Sometimes this requires shutting down LabVIEW.)

If you wish to only run your code, you can simply press the run button on the "robot main.vi" If you wish to deploy it, then it must be built before deploying. The build, then deploy process is manually repeated for every program change and update. (This is why most people simply press the run button during testing, and deploying only when needed.) This process only takes a few moments.

I hope this helps with your problem.
