eLicense Control Error - 'LCC2'

So I updated to El Capitan and i’m getting this error when opening eLCC.

Application ‘LCC2’ has caused the following error:

Connection to protection device lost.

It won’t see either my USB dongle or the soft e-licenser.

I have tried installing/reinstalling eLCC to the latest version, restarting, trying with older versions of eLCC.
The dongle works fine on other computers running both Windows & other versions of El Capitan.

What’s going on?

The screen shots of the errors I get are attached.
