In-app purchases not working!

I got the initial app free a few months ago and my daughter loved it so much I paid the $11.99 for the full Level 1 set (99 words) and ever since the update they havent worked and are locked! I sent an email requesting assistance to fix this or to give me a refund! Looks like Im not the only one this has happened to! Very disappointed!
