Object can not be used after a session

Hi I was wondering if anybody has any Ideas about or has experienced this.... I create a new object and then assign it to a session var $customer = new Customer($_GET['facilityID'], $_GET['customerID']); $_SESSION['acceptPayment']['customer'] = $customer; but later when I access that session var [in the the same file but in a different function and different instance], php gives me an error saying: "The script tried to execute a methode or access a property of an incomplete object. Pleas ensure that the class definition lt;bgt;customerlt;/bgt; of the object you are trying to operate on was loaded _before_ the session was started at <filepath>/acceptPayment.php line 103" I did a little reading (rtfm) on php.net and saw that if session.auto_start is turned on, you couldn't use Objects with sessions. Well I checked my ini and the session.auto_start was set to 0, so I am now scratching my head in confusion. I require_once the Customer class and start the session after the requires and includes, so then I thought ok require_once so I change it to require and then it doesn't load the class the for some reason (sigh). Thanks for your help in advance Matt
