Just to jump on the bandwagen, I have the same problem with limewire, I have ox 10.2.1, my computer is just out of the box as of two days ago. The startup wizard runs each time I startup Limewire, no matter if I have restarted the computer or not. I have reinstalled several times and, I've noticed that I get two text files on my desktop after installing Limewire one called err.txt and the other called out.txt (this one is blank). The err.txt file is as follows:

InstallerModeController: No lock file present.
Extractor Directory Not Found, using 'user.dir'
Default properties location = /Users/david/Desktop/
UI Mode set to Default - SWING.
