Something’s not right but I can’t figure it out.

I bought this app to convert audio CDs ripped to wma and convert them to m4a. While it seems to do a good enough job for this simple task, when I load the m4a files into iTunes, the files converted with this software end abruptly about about a minute for the actual end of the song. The files that end abruptly play normally in VLC, and all my other m4a’s converted with other software play normally in iTunes. My hunch is that there’s a glitch in the bulk converter part of the app, because when I convert one song at a time, they will play normally. But this “one at a time” feature is free with the “lite” version, so I just wasted $9.99.
