Okay, I never ever had trouble with the whole AAC thing... on my old computer. Now, I have a laptop (Windows 7) and when i try to edit the format thing from m4a to m4r I cant because the format doesnt show. Like on the old comp, the format would show and it would be easy (it would look like:"song name.m4a" then I would change it, etc.) now with my new laptop, i dont know where to go to edit the format (it just says the song name) ! Please please PLEASE help
