I used some of my nine coins to purchase a couple maps.

 • Halloween Town

 • Giant Haunted House

and also downloaded for free 

• Alien Dimension

• Skyblock plus

and unfortunately none of them will let me play. I keep getting a message “ there was a problem loading this world.” So I then tried the free ones and got the same message. Also I tried to put one on my realm just to see if it would work that way and that when I hit the second message.(provided in the snapshot photos I sent)
