Well ...
E-onsoftware.com und Cornucopia3d.com are working again ...

But like being told on the simple maintenance info, you should go into the options/settings of your web browser and delete the cookies from e-onsoftware.com und cornucopia3d.com ...

But make sure, you remember your login data - name and password - because you will have to login again on both sides, to be noticed as a Vue user and C3D customer and can use your account.
