Need to update a template

I updated woocommerce and the shop page stopped working.
It turns out that a template was not updated and I need to update manually.

sydney-pro-ii/woocommerce/single-product/add-to-cart/external.php,
sydney-pro-ii/woocommerce/single-product/add-to-cart/grouped.php,
sydney-pro-ii/woocommerce/single-product/add-to-cart/simple.php,
sydney-pro-ii/woocommerce/single-product/add-to-cart/variable.php version 2.4.0 is out of date. The core version is 2.5.0

How do I do this???
GREATLY APPRECIATED.!!!
