Janome mb4 was given to me but the Rcs screen will not turn on. Stopped working after update was told. I see that to operate the machine the Rcs screen is optional. manual says a computer can be used. Im unable to find a screen to purchase so wondering what kind of software will it need to run the machine? I see one called digitizer pro. Is that my only option to just run the machine even if I have digitized files? Thanks
