So, here it goes. I downloaded the Gurk Nukem project to look around how things are done a little bit better, and then started to work on a new project. When it got around to puting together a map, I did just that and tried putting it into UtiLiti. In the console window, it's just saying
Unhandled exception: with no actual error. In the zip file below, I have attached the Tiled Map and Tileset, the tile images, and the crash log from UtiLiti. I'm also using Java 8 so it's not the same problem as before. Lastly, I was able to open up the Gurk Nukem maps in a new file in UtiLiti. Any help is appreciated. Thank you!
That zip file I was talking about: https://goo.gl/Znazbf (Updated, the previous zip did not contain the PNGs like I thought it did.
