I very much agree with Nick Swayne -- call Mindstorms tech support: MINDSTORMS technical support, 1-877-680-2800, Monday through Friday, 8:30 am to 6:30 pm EST We had the screen failure (see my panicked forum entries from two weeks ago) and they sent a replacement -- no hassle and shipped same day. They said it would be 3 days but it was 4 business days (shipped from Nebraska to Virginia).
