Header creation issue

I have an issue with Casey's .emacs file. The issue is when ever I create a header file it does not automatically insert the header guards that Casey's does. I get this error

File mode specification error: (void-function casey-header-format)

I'm running on windows 10 (ugh.. windows forced me to update) 64-bit

If you need more information please ask.
Just in case anyone else has the same problem, I fixed the issue by reloading the .emacs file and now it works just fine.
Now get to fixing your other problem, the damn Win10 being on your PC ;D
