PayPal module doesn't update Payment Status Of Order

[chris_mini_charmed]

Hi, I'm having troubles with the validation of orders using PayPal pro module.

Basically the order is created and saved into the ps_orders table but its payment status is not updated and the order is not saved into the ps_paypal_order table.

Can someone help me?

I examined the module and I understood that after the order-opc page, the paypal module sends the payment information through the submit.php of the integral evolution, then the notifier.php, asynchronously waits for confirmation and validate the order calling the parent's method which calls the validate order of PaymentModule.

Is it right?

By the way, I'm using PS 1.5.4.0 and PayPal 3.5.1
