Getting a Invaild Tileset Reference

[RootBeerKing]

Hello, I've been playing around with the sample files and I finally got around to trying to load some of my own artwork into the engine, however I have ran into an error that I'm not sure how to fix. I've basically taken the Platformer.py sample and replaced the tilemap with one that I have made personally. Everything is the same I just changed lines 64 and 65 the file to redirect to my tmx files. Doing this I get the error "tilengine.TilengineException: 'Invalid Tileset reference'" Any ideas what might be wrong?


Thank you and have a wonderful day.
