Depends where and how you bought it. If you bought it in a store, in Europe, either through a European website or disc in a shop, it should have appropriate markings as required by the trade laws in place at the time. If you bought it from the SM website in the US, the site only needs to comply with US law. Onus is till with the buyer to determine source of product. Your question should probably be whether there is any US requirement to highlight access limitations to software and terms of purchase that don't need a lawyer to understand. Don't forget, the US can, in some cases, tell you absolutely nothing about a product (depending on the state in which it is produced/sold), but if you sue them, can have such wonderful labels like "contents may be hot" on a cup of coffee, and "use like soap" on bars of soap.
