This just started the last time I tried to use my card. When I plug the card in and turn the ESC on...every other vertical and horizontal led on the card flashes and this alternates with every other light vertically and horizontally (hard to explain). The 'link' light does it normal rapid flashing. Any ideas? Will send an email to castle if nobody knows. Haven't tried another card yet.

If you are using the V1.28 software that is the problem. The V1.26 is the lastest software that works with the program card. The card will work with the V1.28 as a link but does not work by itself (in the field). I contacted Castle and they said they know of the issue and newer software is in the works to correct this problem and some others.
