Toshiba Dynadock, Qosmio, latest drivers upgrade --> black display

[jborland]

I have a Dynadock, attached to a Toshiba Qosmio, which prior to upgrading to the latest driver set, was displaying on 3 screens (2 24" Asus monitors and the laptop screen) using Windows 8.

I added the latest driver set as indicated by the Dysplaylink software(in the thought that I would upgrade to Win 8.1 soon), and now the second monitor does not display. The system detects the display, indicating the correct model, etc. in the screen resolution setup, but the display stays black (mouse will go there, but no visuals).

I am attaching screen shots of the device manager, as well as the screen resolution, and the Dynalink support files as gathered by the dynalink tool.
