issues uploading sketches to Seeeduino_ADK_Main_Board

I have tested with IDE 022,023, none of them works, no matter in Windows vista or windows 7. I always get the problem on , " fails to upload with:
avrdude: stk500_2_ReceiveMessage(): timeout"

I brought the board late last year, and tested it and nothing worked out, my previous post was here : viewtopic.php?f=4&t=2776

in your post, your solution doesn’t work. It seems it is easy to upload the program for you, I doubt is there a problem with the board itself?
