Whilst LW is closed, Delete your LW Preferences folder called limewire & found here: /Users/your_username/Library/Preferences/LimeWire
If you're not sure how to locate it, then put your folders into column view & follow the sample below.
Allow LW to settle down before searching. If you have many shared & incomplete files this can take some time.
Don't use the Resume/Find Sources button on more than a few files. Otherwise this will affect LW's quality of use.
Some hints: A well set-up LW can start to automatically continue its dwnlding after it's settled down perhaps 2 out of 3 times you open LW.
