problem installing displaylink core software on Windows 8.1

[superlu007]

I have a Kensington SD3500V. I am running windows 8.1 on a Dell Laptop. My computer prompted me to update my displayLink driver. Now my monitors are no longer displaying. I have fully unistalled both displayLink and kensington video driver. Now, I can't install any either drivers. I am getting the following error message

Could not write value MirrorDriver to key
\SYSTEM\CurrentControlSet\Services\DisplayLinkGA\D evice1.
Verify that you have sufficient access to that key. or contact your support personnel.

I have ran the install as Administrator as well. I have contacted Kensington and they are pointing fingers to displayLink driver.

I am also attaching the support file that was generated by the DisplayLink Support Tool.

Please help
