Customer Info Authentication Error

After I add items to my cart and go to check out I get the the Customer Information Page and get an error that says:

Warning: Smarty error: unable to read resource: “cart_pages/checkout_login.tpl” in /webroot/s/a/saltw002/www/classes/templater/Smarty.class.php on line 1096

The error is over where existing customers can login and I am still able to enter in new customer info. Also when a customer signs up for a new account should an email be send with their password to log back in because if this is the case than it isn’t working for me. I hope someone can help and I appreciate your time.
