My sister and i both have ipads. hers is the 3rd generation, mine the 2nd. We live in the same home, so we share our movies off our computer. any movies we purchase we download to the computer whether we purchsed it from the ipad or computer. we both have authorized the computer and havent had any troubles. i know to directly download movies on my ipad from her purchses i have to wait 90 days which is why we use the computer. when i downloaded her last movie (the amazing spiderman with itunes extras HD- 4GB holy moly!) i downloaded it from her purchses off itunes i didnt transfer. it will not go on my ipad and it doesnt say why? please help me?
