I would look the Janome website and search for machines updates. They should have the update files and the instructions on what to do to make your machine download the file. I download the update files for my machine from Husqvarna-Viking from their website and the files are in zip format, so they need to be un-zipped first, then copied to the memory stick, making sure that there are no other update file in it. Just follow their instructions. Hugs, Lidia.
call your dealer... when I do updates I take my machine to the dealer and they do it for me...
