Capturing Multiple App Layers on a VM

Another newbee question. I'm following the VMware  Horizon Mirage App Layer Capture Guidelines v4.0 on page 9 where it describes the process if you are going to want to use a virtual machine so you can capture multiple app layers. I have followed the steps 1 - Create the clean reference machine, install Mirage Client and centralize the device to a Reference CVD; 2 - Take a snapshot in the clean state; 3 - In the MMC, use the Start App Layer Capture (actually called Capture App Layer in Common Wizards, unless I am mistaken) option... here is where I hit a roadblock. The device is a Reference CVD, but the wizard takes me to select from Pending Devices, and I cannot access the device as it sits in the Reference CVD area. The VM itself also appears in Assigned Devices.Do I need to remove it from somewhere? I'm confused !
