How do I import a match found via Hints

Helen at Darlington

I followed a MyHeritage match from Family Historian, and liked what I found. I selected that it was a correct match, and MyH. provided instructions as to how to get the new material into Family Historian. I didn't entirely understand, so left the job overnight. The tree it was from was apparently on Family Search.

Now I can't understand what to do, and can't find the file on my computer. Will it have deleted? MyH will not allow me to start the process again.
