Have been using the latest version for several days and it was running fine until the popup which always appears with the message "....Limewire is not your default magnet handler..." I clicked 'ok' just to get rid of it. Now, I can no longer add or remove files to share - that option is frozen when I click on add file and also the tools option. Can't figure this one out - very, very odd. Have tried uninstalling, using a previous version and now have redownloaded and the same thing is happening. (running XP on 56k). Thanks for any advice.
