Engine Not Showing up in Game

[SithMurcielago]

I created a new folder for a similar engine, but with a different name and numberlist. I made the changes in all the needed files. When I start a scenario in the game and the new name doesn't show

Help!

did you place it in an existing folder? You may have to add it in the editor.

Have you cleared your cache?

ok I forgot to clear the cache and the name showed up in game, but the game crashed. Any insight?
