I'm having the same problem. I'm on Mac OS9.2.2. My previous version of Limewire worked like a dream, the latest version doesn't do anything and now I can't locate an old version to reinstall! In 3.6.15, any file clicked on says "queued". If I cancel the download and attempt it again nothing happens (ie. the file doesn't even appear in the downloading window at all). Can ANYONE help??? Is it anything to do with specific memory allocations etc??? It's got nothing to do with any settings within the program... I've tried everything.
