I've been following this tutorial: http://kivy.org/docs/tutorials/pong.html. I'm trying to run the program after finishing the steps under "Add Simple Graphics", but instead of a black screen with a white line and two zeroes, I just get a black screen. I copy pasted the code and have the files in the same directory. In the shell it says that it can't find pong.kv in pong_directory, but I checked twice and it is there.

You don't need (or want!) kivy 1.0.9, that's really old - it's only a minimum requirement. The pong tutorial should work fine.
It's not clear what your actual problem is - what part of the tutorial are you running (you could paste the code)? The first runnable example should give a black window (there's no other code there), while the second uses a pong.kv file that is not found in your log.
