I have a Dell D5000 dock with a 6430u laptop. Randomly my dock stopped working. I've removed all software, dock and displaylink, tried the cleaning tool and reinstalling with version 7.9 of software, no luck. I have Windows 7 x64.

My dock indicates connection is good and my usb headset works from the dock.

Problem:
-----------
No display at all from either of two Dell monitors plugged into the dock. The dock D5000 software indicates good connection in software and blue lights on front.

Questions:
------------

--How do I verify display link is installed correctly?
--Should I see a device in device manager?
--Should I go back to an older version of the software? I had 7.6 and it was working previously.
--Any tips or tricks to troubleshoot?

Thanks,
Jason
