Hi Friend.

It sounds like possably a corrupt java download, &/or L/W Prefs folder prob
First! close L/W completly, then Go,
START/My Computer/local disc C:/ Documents & settings/Your User Name/Application Data
Now Delete the LimeWire Folder.

Now! Go to,
START/Set Program Access/Change or Remove Programs,
now completely remove all versions of java.
Now! Use this Link to get (jre1.5.0 10) Use the off line installer NOT the (recormended) one,
http://www.java.com/en/download/manual.jsp[/URL]
You will have to reset your L/W options after.
shout if you have problem Feedback helps everyone
Peace.
