Hey, so I was trying to start up a random game so I could get a screenshot of someone to show off the player skin in my new pack, right?

But every time I try to join ANY server on the list, I first click the "Launch Application" button in the first window that comes up so I can actually play the game, and then not even a second later another window comes up and the only text inside is: "invalid game file."

I did recently swap out all my kv6 files for the game with my new skin pack so I could get the screenshot I needed, but I didn't do anything else. And yesterday it was working just fine. Anyone know what could be causing the problem and how I can fix it?

You can't add extra voxels onto the player model, that might be it.

Oh, alright...
