PEAR:MDB2 NO ERRORS OUTPUT

Hello, I am attempting to use the PEAR::MDB2 package. I have installed the MDB2 package (MDB2-2[1].1.0.tgz) and the MSSQL Driver (MDB2_Driver_mssql-1[1].1.0.tgz). I execute the following code:

<?php
require_once('MDB2.php');
echo "THIS IS A SQL SERVER DATABASE TEST<BR>";

$dsn = 'mssql://login:password@192.168.1.15/mydb';

echo "CREATING INSTANCE<BR>";
$mdb2 =& MDB2::factory($dsn);
if (PEAR::isError($mdb2)) {
echo "INSTANCE FAILED<BR>";
die($mdb2->getMessage());
}
else
echo "INSTANCE SUCCESSFUL<BR>";

$query = 'SELECT * FROM Contact';
echo "ATTEMPTING QUERY<BR>";
$result =& $mdb2->query($query); //execution stops here!
// check if the query was executed properly
if (PEAR::isError($result)) {
echo "QUERY FAILED";
die($result->getMessage());
}
else
echo "QUERY SUCCESSFUL";

$mdb2->disconnect();
?>

The output on screen is:

THIS IS A SQL SERVER DATABASE TEST
CREATING INSTANCE
INSTANCE SUCCESSFUL
ATTEMPTING QUERY

So execution is stopping at the indicated line, but I am not sure why I am not getting any errors returned. Any help would be much appreciated. Thanks!

Have you tried enabling error_reporting(E_ALL)?
If it just stops, that might be because of a fatal error.

If it stops working correctly, it might be that there's something wrong in the object, and a simple print_r($object) usually points you in the right direction.
