I recently purchased an LPCXpresso54102 board that has an integrated Link2 debug probe.  However, I have been unable to program and debug the board using the Link2 probe for some reason.  Steps so far with my Windows 8.1 machine include downloading and installing the latest versions of LPCXpresso and LPCOpen, and then importing and building a simple project, 'periph_blinky'.  However, when I reach the "Debug" step in the process, the following window pops up:

Connect to emulator:  LPC-Link(WinUSB) or RDB-Link
LPC-Link (WinUSB) or RDB-Link not found.
This could be because it is disconnected, not powered, or already in use

As far as I can tell, the Link2 debug has been connected, and a driver for it has been installed.  For example, in the computers Device Manager under Ports, there is a device "LPC-LinkII UCom Port (COM3)".  This device comes and goes in the Device Manager window depending on whether the 54102 board is plugged in.  I have uninstalled and reinstalled the driver for this device, as well as tried a different USB cable. 

Any suggestions?
