Weird error - apache.exe

I get this weird error.
"The instruction at "0x014f7707" referenced memory at "0x00000000". The memory could not be "read".

Basically, i just copied the sample code from the website.
My code is
"
include_once “ez_sql.php”;

// Include the EZ Results Class

include_once “ez_results.php”;

// Perform query and display results
$ezr->query_mysql(“SELECT email, login FROM users”);
$ezr->display();"

I've created a table called "users" and populated fields email & login. I am running this off of win 2k laptop with xampp.

Can you help?

TIA,

Thomas Kim
