Need more sources.
 

Whatever I try to download, I get the message -"needs more sources"

How can I rectify this, I click find more sources and nothing.

Can any1 help? Please

Do the files sit connecting for ages before going to 'need more sources'? If they do, they sound like fakes. These things are all over the network now.
Search again, vary your search terms & stay away from files with heaps of sources...go for a file with 10 sources or less, or those with a modem source.

For video files, make sure to check the file with Bitzi before download. If a file's been rated, you'll see other users' opinions. Files with lots of sources but no Bitzi rating are likely to be fakes.
