error reading file skin.json libgdx

Question

I am trying to create a main menu for a game that my friends and I are are attempting to make. We work with Eclipse + LibGdx, and I genuinely have no idea what I am doing. I am using code directly from, and I have been unable to find any help on any blog/forum/tutorial.

Thanks. Keep in my mind I am completely lost and am on my last resort. Sorry about any mistakes I made in this post!!

Answer 1

That error is basically saying there's something wrong with the skin json.

The format though seems pretty fine, however I think there is more in the stacktrace. Please check out the path to Razer.fnt.

If that doesn't fix it, paste here the full stacktrace.
