Heroes of Might and Magic V map editor – Tribes of the East.

Dear friends, once I opened the map editor for Heroes of Might and Magic V - Tribes of the East. I created a map (without errors). Then, I saved it, went into the game, and looked in the scenarios section, but it wasn't there! :confused:
I've created things multiple times and haven't been able to find them in the game! Please help!:smile25:
