Success! Thank you very much!
My dear friends, you are absolutely brilliant! You all saved me from pulling out my hair in frustration. A directed, I checked on the designs that are preinstalled on my machine and noticed that the large ones were not accessible. Hmmmm! Then I went to the embroidery frame display area, searched for the 6x10 frame, clicked the off button and then the on button again and voila, it now works.
I would have NEVER figured this out on my own. Thank you so much for your help. You didn't have to answer my question and yet you took time out of your day to do so, to help a complete stranger, and for that I am deeply grateful.
Best wishes to you all and many thanks!
