Hey everyone!
I was trying to change the background music in a location, but when I select the file I want to replace (in the sound.MPQ) the "Delete" button is inactive. I checked the security settings and tryed runnin MPQ-editor in admin mode - nothing helps.
You shouldn't edit blizzard MPQ Files, you've said you use 4.3.4, that would be a very bad idea and if you could edit something, there's a chance you may not be able to restart your client again. What you need to do is make yourself a New Custom MPQ Patch, given your Wow.exe is cracked to load custom file patches, and put your files(must be in the same fileformat as well) into that in the folder order like the original so that Wow uses it to overwrite it's original one, also add a number onto the Custom MPQ's filename so that it's higher than 4.3.4's set of numbers(ie: higher than 15595) like call it wow-update-base-15596.MPQ
If your Wow.exe isn't cracked yet, get the cracker for your client over at:
