Minecraft thinks My own created world were downloaded by the marketplace

My friend supposedly bought Minecraft for me, but i noticed a small change. I just logged in and i got all clothing, all texture packs, and after i logged with My account, i opened the world i was working on, and then it said: "Checking download" and it got stuck forever, i knew how it looked like because i saw a friend downloading a marketplace map. After that i replaced it with a official versión from the play store that i bought for myself, and logged in again, and i tried to Open that world again, and it said "Checking download" again, and it never opened again. Please help me with that very quickly, because i want to play My world again...
