CSS SCANNER

Bought it on gumroad now the License Key doesn't work.

Its pricy but saves me a lot of time. Not bad. Please add more features especially on the editor, like rotating elements on the screen by dragging. And open when right clicking on an element

i dont understand anything, i made the payment, i got one license key, now where the hell do i input this license key? I have no instructions on how to save any element, when i right click anywhere, i get no options.... what is this, even your ladningpage isnt complete, can someone help?!
