Loadscreen Loadbar

[Beastwithin]

Hey everyone. I downloaded the art pack from Blizzard and have located the loading screen bar in:

Interface/GLUES/LoadingBar/

I converted the BLP's to PNG, edited them and converted them back. I placed them in the WoW folder directory exactly as it came in the art pack but the loading bar did not change.

I have used this process to change menu buttons, interface textures etc so I know it works. Just not with the loading bar...

I have also been able to modify textures on the main login screen before my char or even account is loaded so I know the game can recognize these files. I have tried looking through the other textures as perhaps they use a different one?

#frustrated. Any suggestions?
