umm... its a wild guess but its worth a shot, follow the thread in the post above yours, about changing one of the files in the arduino IDE. I personaly didn't write any IDE software , but i did change a file in the Arduino IDE because mine was running too slow when bluetooth was on. So the file i changed must have done something to make mine work. some people had trouble with a similar problem with the bluetooth mate. i told them to do the same thing but i haven't got any replies.
