i just installed limewire. i have tried four times to download a song from the files. each time the song downloaded and came up with an error message saying the file was corrupt. how can i tell if the song and file is corrupt before downloading the song. also, how can i hear the song before i download it. i have tried the launch button and it does not work. i have also tried play and that does not work also. can i hear the song before it fully downloads?

any help would be great.
