I ordered a logo pack and we paid for our licensing, but I cannot find where we can download the files, or instructions about where to download them. Where are they located?

When I get the Logo Pack, can I produce Staff T-shirts for marketing/uniform purposes? These shirts would have my logo and company name at the top, the licensed show's artwork in the middle and then show dates and location information at the bottom. On the back, would be the word "STAFF". We would have all staff members and volunteers wear these shirts during rehearsals and all social events to help promote the show. If we are not allowed to do this, is there detailed license information available that specifically says what we can and can't do with the logo pack?

When deciding if we want to purchase the logo packs, is it possible to see the images before we purchase them? Even a small thumbnail, so that you aren't buying something without knowing what you are getting.
