I purchase limewire Pro about 1 year ago. I understood that I would receive updates and tech support for 6 months. When I attempted to enter limewire recently an error message stating that I have an invalid file. It told me to download limewire again. I uninstall limewire and went to the site to download limewire again; I click on the link that stated already purchase limewire PRO. I receive another message stating that my email address is invalid. I'm not understanding! Do I have to purchase the current version in order to use limewire PRO again?
