Do you have the latest version of Java and LimeWire. Go to
www.limewire.com to get the Latest version of LW (or your personal download page if you are a PRO user) and go to
www.java.com to get the latest version of the Java Runtime Envrionment. If you have already done that try uninstalling LW, downloading a new copy from the website, and installing it again. Good luck.
