I have a #$^$%&% Leonardo for free, just pick it up

A few days ago i got a Leonardo becourse i wanted to use it for my new project.

But its now for pickup for free, or i wil trow it out of my car window.

Dispiet all the good advices on the forum and website i gant get it to work.

It wont accept a sketch be uploaded, it says i have com4:, but it tryes to use com3: for programming. Reading the facts and trying to hold the reset until the upload message apears, nothing works. This is a waisted $25

Throw it very very strong thru the window so it lands here :D

This is the error message i get - avrdude: Version 5.11, compiled on Sep 2 2011 at 19:38:36 Copyright (c) 2000-2005 Brian Dean, http://www.bdmicro.com/ Copyright (c) 2007-2009 Joerg Wunsch

Is there a way to get the orgional USB drivers and not the ones supplied with Leonardo?

Which IDE do you use? Have you tried to install the new 1.0.4?
