I don't recommend that you use autopunch for the 150
The designs don't usually turn out well. Your machine can use most any design format.
You would need to by a digitizing software and start
from scratch to learn. It takes time and talent to learn. Not impossible but not shake and bake out a design either. You need to do research on digitizing.
I have the ce250, maybe I can help. You would need the autopunch or editing CD in order to digitize designs.
