Ah yes I think I remember, you were getting COM X not found when it tried to upload? That's the biggest issue that can happen with Due's, it doesn't happen to often but definitely can. I believe it's because the Arduino isn't doing an erase of the memory that holds the sketch so you have to do it manually by pressing the erase button in the middle of the Due while powered up (different button than reset) and then it should upload ok. If that doesn't work you should be able to use the Native USB port on Due, that always works but you can use the IDE serial monitor. When you select the board type in the Arduino IDE there are 2 for the Due, select the one that says "Native USB Port" and when you select the port (it'll be different than programming USB) it'll also say "Native USB Port" after the port number. You'll see programming this way is 10 times quicker than the programming port.
