The queued and requery messages are very common with Gnutella as the big sharers are only a small percentage of the users - ie lots of people wanting to download and few people with available upload slots (especially with heavily demanded files).

There are a couple of things you can do to increase the chance of downloading though:

1. Search again - If Limewire finds the same file on another host , it may download.

2. Kill the download and select it again from the search results list. Don't do this repeatedly, or you'll help to flood the network with request trafiic.
