If you go into your Preferences folder, then open the .limewire folder, and, if there is a FOLDER named limewire.props, DELETE THAT FOLDER. The next time you open Limewire and run the setup wizard, the program SHOULD install a FILE named limewire.props. After that, you shouldn't have any more problems with it. I just tried it with 2.7.9 and it worked. I just downloaded 2.7.9 today, and I am using the free version.
