Can't Program my diecimilia board

Hello have actually zero experience with this, because this is my first board. I’m using an Arduino diecimilia board in combination with Arduino alpha 0010 and mac os 10.4, but I can’t seem to upload code to the board.

I always get this errorcode:

Binary sketch size: 1108 bytes (of a 14336 byte maximum)

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

The powerled is on, and the LED I put in pin 13 and ground is blinking.

the code I’m trying to upload is:

int LEDPin = 13;

void setup() {
pinMode(LEDPin, OUTPUT);

void loop() {
digitalWrite(LEDPin, HIGH);
digitalWrite(LEDPin, LOW);

Does somebody know what problem could be? :-/

Did you follow this?

Yeah did all that, I could try to install the drivers again.
