Sir is correct, I am a Producer and have never Rendered a Sound File of that size.
I can only assume that is the basis of your issue, considering my 512 Texture Set isn't even that large of a File and takes a good while to Download to anyones game.
Nah, when I converted it to .wav it converted the whole song instead of just the section that I edited/formated to have as a .wav, therefor making it such a big file.
