Cannot load metadata tree for a PowerCube requiring both a Series 7 and a cube password

You cannot load a data tree if it is created from a Series 7 PowerCube.

Series 7 PowerCubes require two passwords; one for the Series 7 security namespace and another for the cube itself. The metadata tree cannot load because you are only prompted for the series 7 password, not the cube password. It is common for PowerCubes to have two passwords.
