Although I have Limewire 4.1.5 Pro Beta installed, I've lost patience with the frequent crashes and decided to go back to LimeWire 4.0.8.

However, when I attempt to install 4.0.8 over 4.1.5 I get the error: "You cannot install this software on this volume. (null)

I've tried chucking the Limewire application folder for but as I suspected, the problem doesn't go away because of residual files left on my Mac. I would greatly appreciate it if someone could tell me how to hunt down all the files so I can delete them so I can clean install Limewire Pro 4.0.8.
