arduino sketch upload error

Hi
I've been coding an existing arduino due sketch to communicate with MegunoLink. The sketch compiles ok, but produces the error messages below when I try to upload it:
I have removed and reloaded upload monitor, and have clicked and un clicked its icon on the comms manager.
MegunoLink is communicating with the arduino through port 20, as it echoes test commands sent from the developing interface.
Could anyone help, please?
John

Hi John, did you figure this out? Haven't seen this one before.

Cheers
