I just received a FB Express MKII today (11/29/12). I have the latest V 1.62 Monkey program and all my other Line 6 devices (POD XT and POD X3) are recognized as is my POD Farm 2. I can connect the FB Express MKII to my computer (a Windows 7 64 bit system) and it is properly recognized and connected and the Windows Device Manager shows this as "working properly", but when I start the Monkey program there is no option to select the FBV Express or any other FBV device.
I've uninstalled the Line 6 drivers, uninstalled the Monkey program, restarted the PC and did a reinstall but the problem remains.
Fixed. The RJ45 cable was still connected to the POD X3 and that caused the Monkey program to not recognize the FBV.
