First thing to do is to try to run ControlBoard without dmx interface (usb line disconnected).
Second thing to do is to check that, for an unknwon reason, your lightshow is corrupted:
- open the "home directory" of your operating system (http://en.wikipedia.org/wiki/Home_directory)
- find the folder "TheLightingController" and rename it (to "TheLightingController_original" for instance)
- try to run again ControlBoard
After this test, delete the new created "TheLightingController" folder if existing, and remane "TheLightingController_original" back to "TheLightingController".
Caution: do not delete the original folder "TheLightingController", otherwise you will lose all your lightshows.
