AutoPunch Help

Hi All, i'm a newbe.. I just purchased a Singer ce-250 and I'm using the AutoPunch Software.
The problem i'm having is when the pic is ready to be stiched. the program wants to fill the openings of the letters with white thread instead of leaving them open for the fabric to show through. i've tried saving in a few extentions but all are doing the same thing. i've included a image i'm working with.
Any help would be great!

Thanks!

J
