I'm starting with libGDX and overlap2d, I'm following this tutorial: Runtime Quick Start - Overlap2D setup tutorial. I did everything like the video shows, but when I try to run it, some red lines appear. I don't have any idea about what I could do to solve. Can any one help me?

Here's my console:

Here's my Main class:

Hers my GameStage class:

project.dt: {"pixelToWorld":3,"originalResolution":{"name":"orig","width":1920,"height":1200},"scenes":[{"sceneName":"MainScene","physicsPropertiesVO":{}}]}

MainScene.dt: {"sceneName":"MainScene","composite":{"sImages":[{"uniqueId":3,"tags":[],"x":-7.666664,"y":-13,"originX":85.333336,"originY":85.333336,"layerName":"Default","imageName":"chao"},{"uniqueId":4,"tags":[],"x":159.33334,"y":-10.333336,"originX":85.333336,"originY":85.333336,"zIndex":1,"layerName":"Default","imageName":"chao"},{"uniqueId":5,"tags":[],"x":-7.3333282,"y":157.66666,"originX":85.333336,"originY":85.333336,"zIndex":2,"layerName":"Default","imageName":"chao"},{"uniqueId":6,"tags":[],"x":159.33333,"y":158.66667,"originX":85.333336,"originY":85.333336,"zIndex":3,"layerName":"Default","imageName":"chao"}],"layers":[{"layerName":"Default","isVisible":true}]},"lightSystemEnabled":true,"ambientColor":[0,0,0,1],"physicsPropertiesVO":{}}

Does anyone have any idea how can I solve it?

Thank you
