This is the nature of the network...

A lot of people are trying to download stuff - fewer people are making stuff available for upload. Consequently there is fierce competition for the upload slots out there.

'Requery' means that there are no free upload slots on the clients hosting the file you are trying to download (it can also mean that the client is no longer on the network).

You can search for the file again and find a new host to download from (or perhaps the old host now has a free slot - but it won't be there long).

You can try searching for a different genre or type of file. There may be more hosts or less competition for some files.

Try leaving LimeWire running for a while before doing searches. It takes LimeWire a while to settle on a good set of hosts.
