I can't find my share folder, last time I had Lime Wire it was C Drive/ Program Files/ Lime Wire/ Shared couldn't find it there, or i'll see it there, but there are no files in it, the thigns I downloads don't go to it.

Your shared folder is probably where you left it. lol Whilst LW is open, go to menu Tools>Options>Saving & that'll tell you the name, location, & path of your LW Dwnld folder. Don't set confused with your shared folder that's in your OS folders. Unless of course you selected that to share. To select/find a folder to share go to LW's menu Tools>Options>Sharing & press add or just note what folders you have shared & where they are.
