My enqueue list dissapeared i think my brother did it how do i get it back
please HELP

You mean your playlists have disappeared? They will disappear once you close LimeWire unless you save them. See more about playlists here Playlists & how to create them (click on link)

i mean the whole section of the library

I don't know which folders you normally share, you'd know that yourself. But for your shared folder, go to LW's menu bar, Tools>Options>Sharing & add your default shared folder which is normally here C:\Documents and Settings\"your account name"\Shared

See How to Share Folders (click on link)

sorry I should have put the section bellow your libray that u put songs in (by pressing enqueue) is gone

That may be due to either of 2 reasons I can think of. 1. The LW player has been disabled. Go to LW's menu bar, Tools>Options>Player & make sure option is ticked. You might need to re-open LW before this has an effect on the playlist window section.
2. (a) Click the black arrow at the bottom so it shows both the Library & the mp3 playlist. Clicking the black arrow will show one or the other or both. (b) Or Drag the partition up so it's not hidden as shown below with the red arrow. (btw I changed the title of your thread.)

Thanks for the help it was #2 but i dont know how it happend
How did u get the green skin?

The green skin was the default one for Pro. But you can download extra skins from here http://www.limewire.com/english/content/skins.shtml

Or get custom made ones by searching these forums for links to them or else, go to this forum: http://www.limewire.org/forum/forumdisplay.php?f=58

ok thanks alot
