Limewire to iTunes importing trouble
 

Okay, so I save my music playlist in playlist files m3u in Limewire, and transferred them to iTunes with no problem before. Now, I go on to iTunes, click import, and none of the new lists I've saved show up. I think that iTunes just froze or something, but everything else works on iTunes, like CDs and such, but it won't read any new files or lists from Limewire. What should I do?
