Map wont load!

[Itskody]

I can start a game in custom stories, but every time i click a "level" door, the ones in which move you to a different map, amnesia crashes, and something pops up saying it cant load that map.

So lets say i have a map called testing, it'll load up then when i go to a door and click it, it loads for a split second then closes and a window pops up saying it cant load //custom_stories -> testing -> maps -> Chapter01 -> Testing2.map// Now this was working all day, but it just suddenly stopped.. Any help?
