Can't Upload to freeduino.

Hello I just bought freeduino mega 2560. And I am very new to electronics and microcontroller.

I am trying to upload sketch to my board using usb cable. But the uploading is taking forever. I can't upload sketch. What should I do.
I selected arduino mega 2560 from the board and selected com 5 from serial port.
In device manager it is showing no errors.

Please Help.
