I’m wondering why I’m the only one asking this… (perhaps it would be good to have a faq).
How is it possible to download the materials that are marked as “free”? There is no problem adding a “for credits” project to the cart.
If the “free” projects require credits, what is the difference between free and for credits?
What browser are you using? With Google Chrome and Mozilla Firefox it works, I have just tested.
You should see the download button in the “project page”, the page you reach clicking on the image of the project.
