Lately I had a fantastic success with my Limewire downloadings...90% of my selections end up WAITING FOR SOURCES...it is a brilliant success everyone can envy me...
Logically the sources are never found...and you can wait millions of years and Limewire will still be waiting...
Unfortunately Limewire does not refund to me the time I've lost in searching (whole evenings sitting in front of my computer taking care of just a 4.000Kb file being downloaded)and the time I owe to my family...

Where possible, try to download from multiple hosts. Search topic again to find more hosts. Cancel download & reselect from search results which sometimes sparks the download into action.

Other than that, perhaps 'some' of those files are fakes .. as in the fakes you can never actually download. The spammers host them to tease downloaders & annoy them enough to stop using LW, after all that is their purpose & what they get financially sponsored for.
