How using marketplace stuff

Hey!
First of all, i am new to unreal…

i bought the Subway Environment

and want to ask how i can implement in my project.
Of course i tried to click the button “add to project” but its like nothing happens.

Thanks for your help!!

Make sure the item you bought is available for the engine version you have. Also, to add a content to a project you must a have a project so you can add anything. Create a blank project using a compatible engine version, then click to add to project, select the project to be added to and voala
