The problem with java and starting limewire can be solved by creating a symlink to both the java executable and the limewire executable. Execute the following two commands as root from a terminal window. ln -s /usr/java/j2re1.4.1_01/bin/java /usr/bin/java and /home/your_user_name/programs/limewire/LimeWire /usr/bin/limewire where the path to java and LimeWire represent the appropriate paths to the executables on your system. As far as the problem with the save directory, it doesn't sound like a permissions issue as you said you chose a directory in your home folder. I would delete the hidden folder .limewire in your home directory. You can do this by executing the following command as root or as user, rm -rf /home/your_user_name/.limewire. The hidden directory will be recreated next time you run LimeWire and new preferences will be set hopefully fixing any errors that were present.
