Problems with Bossa and Windows 7

Hello,

I've connected my PC to the Due through the Native USB port. The Device Manager calls it "Bossa Program Port (COM5)" but Bossa says "Could not connect to device on COM5".

So I tried connecting through the programming port. The Device Manager calls it "Arduino Due Programming Port (COM3)" but Bossa says "Could not connect to device on COM3".

If anyone can suggest fixes, that would be great.

Thanks,
Matt
