just use the find command to search "everywhere" for filenames containing "lime"--you should see the two folders where the files are installed. (/Applications/LimeWire and Library/Preferences/LimeWire). It's also a good idea to move or trash old installers out of the way and to really clean things up, trash the Incomplete folder.

btw--sounds like you have a problem with your java---a few of us had something similar after a fresh Panther install.

Just restart the computer holding down the shift key ("safe boot") which will run a filesystem check and repair. Run the disk utility (Applications/Utilities/Disk Utility to Repair Permisssions. Run Software Update to make sure your java is the latest. Restart normally and download the latest LW (4.0.5) and all should be better.

cheers
