HELP with Webclient and simultaneous threads

Hi,
I´m coding an application that is able to download various mp3 files
at the same time.
For each mp3 download i´m using a thread. Each thread uses
System.net.WebC lient.
If i try to download 3 files at the same time, 2 of them starts
downloading (i see in the explorer the size incresing with the time)
however the third mp3 never starts downloading and after some seconds,
application throws a timeout exception in the client.OpenRead (URL);
line.
Below is the code of the thread:

try {
// Get HTML data
WebClient client = new WebClient();

Stream data = client.OpenRead (URL); // HERE HAPPENS
THE EXCEPTION
BinaryReader reader = new BinaryReader(da ta);
byte[] str = new byte[1024];
int intByteLeidos;

BinaryWriter BWEscritorBin = new BinaryWriter(ne w
FileStream(Path , FileMode.Create , FileAccess.Writ e, FileShare.None) );
try {
intByteLeidos = reader.Read(str , 0, 1024);
while (intByteLeidos> 0) {
/* if (prgBar.Maximum 100)
{
prgBar.Value += intByteLeidos;
}*/
BWEscritorBin.W rite(str,0,intB yteLeidos);
intByteLeidos = reader.Read(str , 0, 1024);

}
data.Close();
return 1;
} catch (IOException expIO) {

System.Windows. Forms.MessageBo x.Show(expIO.Me ssage,"Exceptio n");
data.Close();
return 0;
}
} catch (WebException exp) {
System.Windows. Forms.MessageBo x.Show(exp.Mess age,
"Exception" );
return 0;
}
}

}
Any help will be really appreciated.
