sorry I know a lot of people ask the same question over and over agian on these forums but I can't find my answer anywhere

I've hit yes to downloading even though 'Limewire can't find a licence' (on my own head be it) and the file still doesn't come through.

I've tried 'always use this answer' and restoring the defaults and nothing, I can only start the files at the bottom of the search with virtually no peers and they never have 'enough sources'

I'm on a mac and I've just recently changed to a bt broadband home hub from cable broadband, everything was OK before - could it be my firewall settings?
