It must be the bad weather. lol or all the above.

May I suggest you try 3 things:

1. Delete the LW Preferences folder called .limewire (whilst LW is closed!) & found here: Your .limewire folder is in "C:\My Documents"

2. Update your Java version 1.5 (take the JRE)

3. Don't use the Resume/Find Sources button on many if any files. This will result in your files queueing for much longer & several other side-fx.
