I'm using MP3 Maker 14, and it won't allow me to play/convert m4a files I've just downloaded on iTunes - what am I missing? This was what I bought this program for! Thanks
What do you mean by "downloaded" on iTunes? Do you mean you actually downloaded them from the Internet using iTunes, i.e. you purchased them from the iTunes shop? In this case you wouldn't be able to convert them for legal reasons, because it's most likely protected content. The file extension is probably M4P, too.
it's because iTunes has it's DRM protection to prevent you from playing or converting music on it, you have to download a converting tool to do the work
