DUE problem while uploading [SOLVED]

Hi!
I have recently bougt a DUE, my first time with this board...
But, when I try to upload something, examples, etc, i got this msg:

bossac.exe: extra arguments found
Try 'bossac.exe -h' or 'bossac.exe --help' for more information

I tried in 2 PCs, 2 board manager versions... Always the same

Any idea?

Thanks, and sorry about my English :stuck_out_tongue:

Re-install Arduino IDE and platforms?

Solved!
