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

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Do you have the board and port selected in Tools?

You blew past the Read Me Before Posting thread, how about the IDE directions and past forum threads in the topic

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

Did you try the suggestions? What were the results?
