I'm sure this is somewhere else in this forum, but there's just too much & not enough time to look. I just downloaded a few songs & was having trouble transferring them over to iTunes. Then, I logged out of Limewire, & now those songs are gone. In fact, they never made it to the library. I made the mistake of upgrading my Limewire, then didn't use it for a while. I wasted a bunch of time trying to make this work, & it used to before. Please, help me.

Unless you've accidentally deleted them, your downloads will be there. The location of saved & shared folders changed in later versions - check out this link
If you've updated LW and can't find your downloads!
