Windows 8.1 DisplayLink Network Adapter Error with 7.4 M2

I’ve lost Ethernet connectivity on my USB 3.0 port replicator since upgrading my HP Envy L/T to Windows 8.1 from V8.0. I’ve installed the latest driver (V7.4 M2) but I am still unable to load.
Device Manager indicates an error with the following message –
“This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)
An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system's image of the Registry.”
When I move the LAN cable from the replicator to the PC it works fine.
All other ports/devices are working without any problems.
DisplayLink manual for the Driver Key has the following-{4d36e972-e325-11ce-bfc1-08002be10318}\0022, yet the registry entry is {4d36e972-e325-11ce-bfc1-08002be10318}\0021...cannot change.
