Why can't I upload the sketch to my Board?

I am using Roboduino board, Whenever I am uploading the blink sketch I am getting following errors. I am using the board from quite some days. But problem is occuring from now onwards.

I have selected the right board - Arduino Duemilanove or ATmega 328

(With wich I am working from long back)

I am using correct serial port COM4

(I have removed the cable and reconnected it to confirm the port it is COM4 only.)

I have removed every connection to board (pin 0 and pin 1 are free now)

What might be the problem? How to resolve this?

The error I encountered is

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x8d
avrdude: stk500_recv(): programmer is not responding

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

"# I have selected the right board - Arduino Duemilanove or ATmega 328"

The documents from the manufacturer say ATmega168. It is possible that someone updates the processor to an ATmega328P and maybe they installed the Arduino UNO bootloader so that's worth a try.

did you figure it out? I'm getting the exact same error codes.

Yes, I figured out.

in the Tools-> Processor -> use the Processor with 'old bootLoader"
