The Arduino IDE cant access the program file "avrdude" for some reason. Maybe re-installing Arduino IDE will fix it? Avrdude is used to transfer the program to the arduino board once it has been compiled.

Like Buzz Lightyear in Toy Story 3, your Arduino Leonardo must have a Spanish mode. 
Press the reset button, and it should be able to connect. Look at the port in the Tools menu of the IDE. It should show a port - be sure it's attached to that port.
