Stale Trade

I've got a stale trade that is complete but the other end of the trade hasnt clicked that they sent anything so I cant click that I recieved... So I cant close the trade. It was just some freebies to a new player (I just asked for the $ of shipping that many cards in a bigger envelope which he provided promptly)so I dont care about the feedback I'd just like to get the trade off my Overview. What do I do?
