Can't upload to my board

Hey there! I'm kind of a noob when it matters to arduino so i was hoping you guys could help me!

I'm using seeeduino ADK and i can't upload a simple sketch to the board. I've tried on windows 8, 7 and Ubuntu.

I always get these message:

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer

When I connect the board to the PC via USB I have two red leds on, the ones from RX TX. I press reset button and nothing happens.

Can you please help? I've read the troubleshooting already but it didnt help!

Have you tried contacting seeed studio? Sounds like perhaps no code on the USB/Serial chip so it's not responding, thus the Red Rx/Tx LEDs on.
