I'm having trouble with my Macross Fever machine. When I press the black ball release button, it does not depress completely, and no balls come out. When I open the front, and press down on the white ball release mechanism, the balls do come out. I don't see how I can get at the problem and/or I jam the balls? Any help on this one?ImageUploadedByTapatalk1366851309.054443.jpgImageUploadedByTapatalk1366851323.039167.jpg
