Can't add m3u playlists to iTunes 11.0.3.

Hello,

I have installed the new version of iTunes - 11.0.3. And now I can't import my m3u playlists to iTunes. For older versions I don't have any problems and just dragged a m3u file to iTunes playlist and everything was ok. Could you help? How can I add my m3u playlists to iTunes?

Thanks.
