I meant if the inputs you are trying this with aren’t already licensed/paid.
The login I mean is the one you have been paying your credits with, please do make a clean sign in on our webpage and go to https://www.capturingreality.com/my.transactions# to see whether there is any credits balance. If there is the balance you expect then log off the application and login again under the same account to make sure you’re not using a different account now.
Also please provide me with the text written in your script to make sure it is done correctly.
