How did you launch the GUI? Did you run the function file associated with the GUI or did you launch it by double-clicking on the figure file? For GUIDE GUIs you MUST run the function file; it performs some setup that is necessary for proper execution of the GUI, and double-clicking that figure file doesn't perform that setup.
