I am suffering from this problem too.Don't worry, I realise that you were not dissing Chord.
I think that i have read two or three posts, mentioning issues with the driver for the Windows 10 update.
Interestingly the issue gives the appearance that the root cause is not that the driver code does not work, but that the signature has not been registered.
Sorry, but I cannot remember anyone posting a solution.

If you find the solution, please share it. Thanks
