woo commerce

Hi

I’m trying to utilize woo commerce for the product displays in a website build but each time i activate the products on a page the page then becomes blank…

i noticed this message:
Your theme (Highend) contains outdated copies of some WooCommerce template files. These files may need updating to ensure they are compatible with the current version of WooCommerce. You can see which files are affected from the system status page. If in doubt, check with the author of the theme.

and further going into this error message:
HighendWP-3/woocommerce/content-product_cat.php version 2.5.0 is out of date. The core version is 2.5.2,

is there a simple fix for this via update? not to clued up on how to manually do this…
please help
