Fixing for MoP

[Whoboom]

I've been gone for a while. When I come back, MoP is out, and requests pour in for me to fix the add-on I Frankensteined together. It's just a small one that plays "TOASTY!" from Mortal Kombat whenever you get a crit. I've looked at the function pages and whatever I could think of to find out how to fix it for MoP. I need help. I got help from here a while ago when I first put it together, and had to modify it a few times with patches. Now I find I need to fully as the smart ones for guidance, or a slap to the face if that's what's called for.

Please will you help me?
I attached all code files.
