I'm trying to install the Google Rich Snippets Module and when I go to install it it gives me this message.

Patches cannot be applied, because the files which are to be patched, have been modified before. Do you want to copy the pre-patched files over the old ones or to cancel the installation?

Copy
Cancel

Warning! Copying patched files over the old ones may break your store. If this happens please copy the contents of the /home/learnio5/public_html/store/x-rich-gsearch-results.backup directory to your X-Cart installation directory.

What exactly does this mean and what do I need to do to successfully install this mod without breaking my live store?
