Oops. Forgot to add one necessary instruction in the last post. The LimeWire Pro v2.7.3 installer and the Set-up procedure that followed left an empty folder inside the ".limewire" system preferences folder named curiously enough "limewire.props". I trashed this empty FOLDER and REPLACED it with a copy of my previously existing preferences FILE "limewire.props" that I retrieved from a backed up system file. Sorry for any confusion...
