Help with sprites in kartmaker

[Bluecheese]

So I've been getting this massage every time I try to test run my sprite.

I'm extremely new to all this and have only ever modded TF2 to add some hit sounds.

I'm not sure if this will help but here's the sprite I wanted to test.

If theirs details that I left out please ask me about them.
I'd be more then happy to take some more screenshots.

Well I messed around a bit and I think the problem had to do with the name.
I know some coding languages are pretty cap sensitive so I just removed them.
hopefully this help's anyone who has the same problem.

So, just to be clear, are you saying that you changed the name of the output wad to make the "KC" lowercase?
