Has IFI said anything yet?
I'd be inclined to agree with that. Short protection can only do so much for microcontrollers, their IO pins are only really meant to source low current draws (typically less than 100-200mA). What voltages are you using it with? If you have greater voltages on board than the RC's logic voltage and they got shorted onto an input it could very easily blow it out. I had this problem about a month ago in one of the designs I was working with where a 12V line got shorted onto the 5V bus taking out two micros and an LCD, even though the short was only for about 1-2 seconds. I hope you get it fixed but from the sound of things it may not be doable unfortunately.
