Weird, two forum threads about purchases from the same store. Thanks for your purchase, I'm sure we'll be able to get things figured out.
Is this is a Blinky POV or Blinky Grid? Are all the LEDs lighting up during the demo program?
Please attach a photo of the top and bottom side of the kit if you can. I think the forum software now allows for image uploads, but let me know if it doesn't allow you to upload images.
Take a look at this programming guide and let me know at which step your kit behaves differently than described in the guide.
In step 7, does the second LED flash regularly as the on-screen squares flash? In general, if the led doesn't flash regularly during programming, then that indicates an issue with reliable data reception by the clock sensor. If you get regular led flashed during programming but checksum errors at the end, that indicates an issue with the data sensor.
