Greetings,
To log into CV-Toolbox, you will need to enter the same email address and password as your Cineversity account.
The most common occurrence of a log-in failure is when a user tries using a username instead of an email address. Also, accidentally making multiple Cineversity accounts with different emails, and trying to login with the incorrect email address has been a reported problem as well.
If the above isn’t the case, we’ll need a little more information to help diagnose the problem.
What version of Cinema 4D are you installing CV-Toolbox on? Is the system you are running CV-Toolbox on have strict or unusual firewalls settings?
Is this a recent install of CV-Toolbox? If this is an older install of CV-Toolbox, we recommend deleting the old version from your system, and installing the most recent version.
Best,
~Michelle
