Arduino BT - Serial port service not running

Hi, I am having difficulties connecting my arduino bt to my computer. When I try to create an outgoing COM port (using windows 7), I select ARDUINOBT but I receive an error that reads, "The device you selected does not have a serial port service running." Is there something wrong with my arduino bt? I tried resetting, but still no luck. Also, I am running it off of 3 AA batteries.

Thanks! Skye
