Song won't play in Limewire or iTunes
 

I am using Limewire 4.2.6 on Mac OS X and when I download a song it won't play in limewire, and in iTunes it won't play either, and says the song is 25-45 minutes long. It use to download that way only once and awhile on the old version but when I updated, now it's for every song I download, no matter how many times I try to re download it. Even when I restart it eventually comes back again. What can I do?
