According to the tutorials my Xapt3r is installed properly (3 blue leds and a brief flash of the red led). However, when I place the 2.6 on top of the Xapt3r, I get blue leds, but the red D0 on the Xapt3r is not illuminated. The reading I have done indicates that w/out a chip installed on Xapt3r, I should get the red led momentarily (which I do), but that with a chip (my 2.6) I should get the red led constantly (which I do not). The problem shouldn't be with my D0, because the brief red led indicates that it is properly placed. So what is the problem? Thanks...
