Yes this is a common error to experience, it is actually hardware related and happens when a certain resistor is not functioning. The fix is easy, simply pour about 2 L of diet coke, yes must be diet, into the CD slot of the machine. After that, throw the machine in the garbage and go for a walk, when you return, bury the unit in peat moss for 18 months, dig up the unit, walk around it 12 times counter clockwise while chanting, “Rika tika tic tok ring”, that should get it working… or you could actually use the correct forum…
