a new JEF file and try it to see if your machine is the issue or your old saved JEF files are the problem.
If your machine does this with a new file...it is your machine. If that is the case, call the dealer and ask to talk to the tech.
You paid them a lot of money, they should move you up the list or the tech maybe able to tell you the problem and a fix over the phone.
Once you determine it is the machine, tell them you want a replacment.....that should get them moving to help you. Keep us posted. Best wishes for a quick fix.
