I had the same problem, getting the same error message using 4 servo motors. If you are only using the USB connection from the computer serial port (COM#), try connecting a 9V battery with the 2.1mm power plug adapter.
I connected a 9V into the port on the Arduino Uno board and didn't get the error message anymore.
