Hybrid Eucon stopped functioning
 

This week, for no reason, Eucon stopped working on our S5 Fusion running 6.0.3 and our Nuendo Pc Windows 10 64 bit.
Nothing had changed software wise.

We can connect to the DAW, but then no tracks appear on the 401 and smartswitches that we can see on the 401 just don't work, neither do the transport or automation panels to which we can still attach the DAW.

Any ideas?

I have already reinstalled Hybrid, as well as the Eucon WS on the PC (tried 3.3.2 and 3.4, same result)
