A Question Regarding downloading And Queues
 

I've been using Limewire for a while now, and I have had absolutely no problems with downloading what I want, but I have had a problem recently when I download off certain users. My problem is when I download from a user I'm able to download a file, and for some reason after like 5% completion, my transfers stop and I'm on a "waiting on busy hosts list" what gives for like 5 hours and nothing happens. How can someone cut in front of me when I download something before they do or is it safe to assume, the user is offline or they are somehow blocking me from downloading from them? thanks
