eleven board can't be seen by xctu

When using XCTU: If I connect the Arduino board/with shield for the first time after boot, XCTU can see the wireless module. however if I unplug the arduino board from the USB port and reconnect it, XCTU can no longer see the wireless module. However the Arduino IDE can still see the Arduino board.

OS: Windows 7 Home Premium (64-bit)
Arduino Board: Freetronics Eleven (uno)
USB Driver: Freetronics USB driver version 2.2
XCTU: Latest version
IDE: Latest version
XBee Shield: Seed Studio V2.0a
XBee Module: WiFi Series 1

I’m brand new to Arduino so please forgive me if I have missed something obvious.
