Pay Per View translations & PayPal checkout

1. So I’ve signed up for the free trial and am liking it so far. Adding the language sounds easy. Just – I have a hosted WP plan (GoDaddy), which means that I don’t usually manually upload files. Can you tell me how to do this for the two language files?

2. My BETA testers report an issue with language. our Pay per View is linked to a Spanish PayPal account (whose preferred language is set to be English). Nevertheless, if you click on a button to subscribe (Express Checkout), you end up on a PayPal checkout page in Spanish. Is there a way to set it up so that those navigating our site in Spanish get to the Spanish PayPal Checkout page, and those in English getting an English Checkout page?
