True Craft texture pack

I purchased the True Craft texture pack. It will not allow others to join my world.

They get a bite screen error ce-34878-0 from PlayStation. I had to have some purchase the pack also just so they could join me which seems like I should not have to buy an my friends a pack just to play also it loads in with pink and black pixels which I read means it did not downloadadownload correctlyIcorrectly, but I not delete it tocto redownload it to fix it
