Nice desktop pic! Update to the most recent Java: http://www.java.com/en/download/windows_automatic.jsp Can you give us some more details. What have you done to your comp since last time you used LW? OS updates? Security patches? How much ram do you have?
If still probs after updating java, then delete your LW prefs. LW Prefs are/should be in a folder called '.limewire' note the dot in front. For me they're in Documents and Settings/User Name.
