it says that the music is in itunes library and it isnt there... im on windows vista... limewire was downloaded on a different account... any help?

Do you mean that you see the shared "LimeWire Tunes" in iTunes? That's just a playlist, those files aren't in the iTunes library Go to your LW library, highlight a file & then click Explore...your saved folder will open. Add files to your iTunes library from this folder.

There's more info in this thread.
Transferring music to iPod & iTunes

No.. I Go to my computer prgram files limewire itunes library and all this music is there, but all the new music i download isnt there and i dont know where it is... and when i search for it nothing comes up.

A couple of other Vista users have had trouble finding their files. Read these 2 threads & hopefully something there will help you!
