You know everyone at some point understands how stupid he is 
Now that i got on track, i download Arduino and TeensyDuino (since the board i was talking came out to be not Arduino but Teensy 1.0) , i did made all the changes required but now I am stuck at an error I cant find any info for :
This report would have more information with
 "Show verbose output during compilation"
 enabled in File > Preferences.
Arduino: 1.0.5-r2 (Windows 7), Board: "Teensy 1.0"
