Help, am having the same problem
imac fp, 10.2.3, 1gig ram, had an earlier version of limewire that worked ok, and now this new one won't even install. tried to open the .zip from within unstuffit 7, but it still won't install...

double click LimeWire_Installer, the dock icon comes up and bounces around for 5 sec. or so, then quits and creates 2 text docs

err.txt (with this text)
InstallerModeController: No lock file present.
Extractor Directory Not Found, using 'user.dir'
Default properties location = /Users/paulblanchard/Desktop/
UI Mode set to

out.txt (with NO text)

what does this mean? Gnutella, is there anyway to solve this problem?
thanks,

megs
