I took a look poking around in your layer this morning, and it may need more than just a quick edit. You have duplicates of things, and that may be causing the compiling issues you're having because of ... strange arcane behind-the-curtain hand-wavy stuff. To get this to work the way you want, someone may have to go clean up the code to the point where everything is only in there once.

You mentioned this came "pre-hacked." Can you point a finger at the source and maybe we can lean on the original hacker? :)
