I have just bought a used Janome 350e with a Digitizer 1.0 CD for the software. The person I bought it from gave me a HASP4 M1, which appears to plug into the computer however the other end looks as though something should plug into it. I am trying to see if there is something else that is supposed to attach to this. I have never used a embroidery machine and not familiar with what is needed to run the digitizer program. Any help would be greatly appreciated. I have been told about a dongle however I am not sure what this looks like or if that is what I have. Thank for your help.
