Last night I clicked on Stop Sharing Folder because I thought if I just stopped that it might help with a song I was trying to download

My first mistake...I planned on activating it again but it disappeared from my Library.

Can anyone tell me what I did wrong and how do I get it back on my LimeWire. I can find it in my program file but don't know how to get it all back so I can start sharing again. I'm so confused!! THANX!!
