Weird... I think it's because of an image with the letter â in the name, and your pc doesn't support that.
It happened to another user with a different game, and he had a japanese-modded pc. Is this also your case?

Mh... i fear that with those fonts images with accented letters had their name changed. I think that if you watch in the image folder the image called "0âtâHâO3.png_" changed name. Hilariously, it's called like that because it was converted from a Japanese name, which my PC don't support. XD
Knowing this I'll update the game removing accented letters from file names. But I can't update it until the contest ends, I'm sorry.
