I'm running Limewire Basic on an iMac (OS 9--old skool). I've been using it for a couple months with no problems, but now, suddenly, everytime I try to download a file, I get the message, "need more sources." I've read a lot of posts here and tried several things, to no avail: sharing more files, changing my download options, downloading files with many sources, clicking refresh, downloading a newer version of the software. I don't know what to do next. Help? Thanks.
