If you get an error message that reads, Floppy disc fail... Press F1 to continue or DEL to enter setup.
Unfortunately, this error is an indication that the computer in your carriage is starting to fail because of age. However, you can use a workaround.
Locate a USB keyboard.
When you get the error message, unplug the designs thumb drive and insert the keyboard into this same port. Use the keyboard to press "F1" and the computer should continue launching. You can then remove the keyboard and replace it with your designs thumb drive.
Ultimately, look into upgrading your Pro-Stitcher Tablet. Here is a link for Tablet upgrades on the Handi Quilter website.
