WholeinYou Hi.
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.
If you cant find Application Data Folder,GO to Tools/folder Opions,& tick,show hidden folders,
You can put the setting back afterwoods to protect your computer.
note: You will have to reset your, Tools/options in L/W Later.
Now! Go to,
START/Set Program Access/Change or Remove Programs,
now completely remove all versions of java.
Now! Use this Link to get JRE 6 Use the off line installer NOT the (recormended) one,
http://java.sun.com/javase/downloads/index.jsp
Disconnect from internet, close ALL apps n reinstall java.
Follow thease instructions exactly.
Dont forget to reset your options in L/W, Licence warning n stuff.
Your feedback will help others
Any Problems Shout.
Peace.
