Dear Users,

I would like to say Hi to everyone. I have Melco EMC6 embroidery machine. I had been using Wilcom program to send embroidery designes to machine before my machine broken down. I do not know what is happening. When I turn on machine machine displays EPBIOS and UNIT NUMBER and that is it. I tried to change unit number but nothing happend. When I try to send embroidery design to machine it says that machine is not connected to the computer.

Can anyone help me, please?
