i have 2 Melco XTS embroidery machine. when opening Amaya OS (I have version 10) for one machine there is no problem. when i start up other machine the software is giving message ( Encountered an improper argument). I cant load designs properly (delay), change hoop, this machine doesn't give any maintenance messages, thread break messages, etc. other machine became affected by the same when this one is on. I re-installed SW, but no result. please help to understand and correct the problem . it started last week.
