After I did that every time I try to open up the communication between machine and computer by inserting my dongle in the machine and connect usb wire from machine to computer, I get an error message saying control and dog (dongle) not same. Obviously the machine is reading the picture file I installed instead of the dongle. Question: how do I remove this picture file from the machine?
