inability to license

Please tell us the asset ID and the error message that you got. You should also state the country you are in, as some assets are restricted and cannot be licenced in all countries.

It is also of use to know if you tried to licence from the website or from inside an Adobe software like Premiere.

You're going to have to provide more info about the issue if you expect a useful response. Show a print screen of the error message you're receiving.
