Mega ADK - Win 7 - COM port not available to select - SOLVED


I'm having a problem where the COM port (COM4) where my Mega ADK is connected is not available for selection in the programmer, but COM3 shows up in the list. Device Manager tells me that COM3 is "Intel(R) Active Management Technology - SOL" and COM4 is "Arduino Mega ADK R3". My driver is up to date, and this was working last week. The only potential system change I can think of is that I've played around with MIT App Inventor since installing Arduino. Any help would be appreciated!

Thanks, noisynoise

SOLVED - I deleted the Arduino driver, reinstalled the software and then updated the driver, all is well for now!
