Trouble COnnecting to Bluno Mega

Hi,
I have the following configuration.
1. Win7 64 bit.
2. Bluno Mega V1.0
3.Micro USB cable.
4.Arduino studio V1.63.

I recently purchased the Bluno Mega Kit and tried to upload a simple LED blinking program .
int led = 26;
void setup() {
// put your setup code here, to run once:
pinMode(led, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000);
}

I am getting the following error.

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

I have the driver installed on COM13.

I updated the driver following instructions from the arduino forum.

Do I have the wrong cdc driver ? can some one share the right cdc driver please if that is the case ?
I am using it on a time sensitive project so early help will be highly appreciated.

-Best Regards,
