So Disappointing

Mine craft is awesome I will say, I love how pocket edition is now with the new material that is available to us but I do have one issue, when I updated mine craft recent version 1.0.4 my texture pack told me I had to purchase it again. I am disappointed because Ive had to buy it twice already and now this is the third time. If you could fix this issue I would really be happy thank you.
