uartsbee & stalker v2.3: avrdude: stk500_getsync() Problem

Hi all

I really need your help. I just got the Seeeduino Stalker - Waterproof Solar Kit and the Uartsbee v4.0 and tried to connect the with my computer windows 7. The drivers were installed by windows and everything seemed to be fine.
Although, I never can upload any code. I always get the following error:

avrdude: stk500_getsync(): not in sync: resp=0x00

I have the correct driver (FTDI, Version 2.8.30.0, Date: 7.12.2013), the right port (COM9, but I tried several others), I tried different Baud rates in the hardware settings and in my code. When I upload my code, the TX and RX on the uartsbee are blinking and the PB0 LED on the Stalker v2.3 stops blinking for a moment and after the error starts blinking again.

Can somebody help me? I really really want to use the Kit now

Anyone??

Hello,

This error occurs if you chose a wrong board.
At arduino Gui try tools-> board -> arduino Pro atmega 328.
The Stalker must be connected via the Uartsbee, an a cable ,i assembled a cable by my self.
Tell me if it works !
