I needed a repository for downloads, Tyle Postle came up

I needed a repository for downloads, Tyler Postle came up with the idea of using Marketpress (It is perfect by the way, thank you Tyler)
I am however having a small issue, I wanted to remove pricing from products entirely (Not needed for this purpose)
Tyler suggested adding some custom CSS to a custom CSS plugin

.mp_grid .mp_price_buy .mp_product_price {
display: none !important;
}

I added that but all it does is remove the price from the grid but not the actual product page, example -

It is the last of the problems i am having, and having searched, that CSS above is the common answer.

Keep in mind here i am dumb as dog sh*t and it has taken me the last few days to actually theme it very basically to fit with my site (I am no developer hahaha)

EDIT*
One other tiny issue

Cheers for any help
