Error message whilst trying to upload sketch to a MultiWii flight controller

Hi everyone,
I am trying to build a drone, and have finished the construction, but I am encountering a problem when trying to set up the MultiWii flight controller, this is my first project and I don't know much about this type of stuff so sorry if I do not post the required information.

Flight Controller: MultiWii 328P Flight Controller w/FTDI & DSM2 Comp. Port (Radio Control Planes, Drones, Cars, FPV, Quadcopters and more - Hobbyking)

Error Message (when trying to upload to the board):

avrdude done. Thank you.

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

I downloaded the sketch from the MultiWii website, and edited it to fit my build as best I could. I don't think the error is to do with the sketch itself, but with the settings. I am using the COM3 Port, the Arduino/ Genuine Uno board, and the Arduino ISP Programmer, in the tools tab.

Thanks in advance for any help.
