I'm using PE design 10 embroidery software. An 91/2 X 14  hoop.  on a Brother Innov is 6500.  I write the design to a USB - transfer it to the machine an it is not there.  I've tried resizing to make sure it is in the frame, but no luck.   the machine will allow me to "build' a large frame design on the machine and to transfer a purchased large design, but not my own.  I don't know what I am doing wrong.

What size does the design have after changing the size? Perhaps there is a problem here. If not, try sending the design to the embroidery machine first without changing the size.
