Of course you can try and research for the file; as I said, it is possible that the host of the file has deleted it or moved or renamed.
And you also need to consider that people all around the world share their files using the gnutella network. That means that the host of the file might be in a different time zone and might come online some time.
I even had situations where I had downloaded up to 80-90% of a file, but in the end I couldn't finish my download because the one host of the file didn't come back online or did one of the other things I mentioned above.
But that's the way it is,.......
