Media jukebox sync error

[ABenz99]

So, I'm trying to sync songs onto my phone with media jukebox, and after a while, a bunch of the tracks started saying "error" instead of complete. They are all mp3 files, and I am using a converter to convert them to a lower bit rate so they fit on my phone. Does anyone have any idea what might be causing this? Most of the tracks were converted and transferred just fine, but some have the error message.

Also, I'm using the L.A.M.E cbr/abr encoder to convert the bit-rates. I don't think the encoder is the problem because the other tracks worked just fine, but it might be helpful to know.
