hello all I am trying to get thewave shield from adafruit to work butwhen I try and load any sketch that works when the wave shield is not installed I get the not detected error with wave shield attached here is a sample of coding that will run without but not with the wave shield the error I get from the compiler :avrdude: stk500_getsync(): not in sync: resp=0x00 its like windows doesnt see the device anymore.
