Rhino 6: Signing in to your Rhino account has expired

Can not open Rhino 6 anymore:

And what happens if you punch the “Jetzt Anmelden” button?

Spinning Ball. Quit after ten minutes


Similar problems on my Windows-Laptop. Message that the login expired, then no sign of V6 on my HDs. Ran repair incl. restart from software panel twice without success. V5 and WIP are still working. Now trying a new installation of V6…
Edit: Haven’t tested much, but V6 seems to work again.

I did it the same way. Works again. But wat happens?
