Every time I have tried to install Limewire on my Mac with Os 9.1 I keep on getting the same Java message that it has caused an InvocationTargetException and cannot not install LimeWire on my computer. I have dowloaded the latest version of Stuffit Expander and I also increased my memory size, NOTHING works!!! Please help! The following Java message appears:
