If you are trying to login to our website, that is not how you access the Tube Toolbox software. That is for accessing a Tube Toolbox Profile which is used to manage your subscriptions. A Profile has nothing to do with operating Tube Toolbox software for your YouTube account. You can't perform any automated actions from a Tube Toolbox Profile. Its only purpose is to help you manage your Tube Toolbox subscriptions. See screenshot below.
