Answer 1

This means that you are trying to use a feature or setting that is not enabled on your demo account. By default DocuSign enables all features on demo accounts so I'm not sure how your account got into a weird, semi-activated state.
In most situations this needs to be fixed by DocuSign on their side by someone going into your account and enabling a feature or setting.
I've gone through your account and enabled some things that should have been turned on, please try again.
