How do i change the combat text?

[Mutilated]

Hey!

None of the addons that's made for this is working anymore (all are outdates). Nice damagefont. Krys damagefont etc.
I was told i can change the font "in the wow folder". Took a while to find it but i guess it's "Blizzard_CombatText.pub" i need to open? How? Cant open it as a normal text document.

Would really apprectiate any help with this. Hate the normal font.

Thanks!
