I'd check that all your refnums all match and are correct. That's a common error. And I'd check that your safety isn't tripping (like Greg suggested). Check for code that takes a long time to execute (one iteration of your Teleop VI should take ~20 ms, the amount of time it takes for a new DS packet to reach the robot).

And once you get access to your robot, if there's an error, the error message should tell you exactly what is wrong and which VI it's located in.
