Go to your LW preferences>iTunes>Importing & make sure this option is still ticked. It might be an idea to untick & re-tick & press apply.

There are occasions when iTunes stops importing. These are due to (1) LW being too busy. (2) iTunes doesn't recognise the format.

I use the Ogg Vorbis plugin & it works.
