Custom scenario hangs on load screen

When I try to play a custom scenario I made, the game is stuck on the loading screen forever. The narrator reads the entire biography, the music plays, and the cursor continues to animate. I've googled and this seems to be a common, but never answered problem.

Thanks

Without the actual mod / custom scenario, this will be impossible to answer. See the link in my sig for how to zip and attach a mod to your post.

Also, is this plain Civ (aka vanilla), Gods & Kings (G&K) or Brave New World (BNW). And does it require any DLC, eg Denmark, Korea, etc

My database log looks like this after i loaded the mod:
