I am having trouble following the steps to get the end result.

Here are the steps I have done:

1. Imported the PNG image and then selected it.
2. In the tools menue selected the Edge trimer.
3. waited for the prompt boxes and said yes to each.

No new image appeared and my imported image remained unchanged? What am I missing ing steps? thank you.

I have down loaded the shape bender files but can not figure out how to get into the program to work. Does anyone know the steps?
