This problem is in the Gnutella network, not in Limewire. Limewire can only download from hosts that have available upload bandwidth and cannot afford to clog up the network with requeries every 30 seconds. I've sometimes had files sitting with Requery for several days and then suddenly start downloading. As I said before, try searching for the file every once in a while and if Limewire turns up another host with the same file, it may download it. If you want to download a popular file, the only answer is to have patience.
