I have had a SE400 for a little over a year now. I use the PE basic with it. I have the connect cord for the computer that I received with it but quickley learned that the basic is the way to go. If you use one of the designs on it and you want to put another in its place you can do that or put all new designs on it. I will put several designs on it when I am doing projects. When finished I will take that design off and add one more to the list. PM me if you have any questions. I will be glad to help if I know the answer.
