I also want to use Art and Stitch so i can pass designs directly back to the ProStitcher. I have received the activation code from A&S. (I do know that you cannot use the @ sign in the fields for the activation code or the button remains grayed and will not work.) I however cannot get it to work on my Pro Stitcher Tablet as it remains grayed out after all of the data has been entered into each field. I have tried it many many times but the app defaults to demo mode. The button remains grayed out even with the code entered. There seems to be a bug. Is there a work around?
