Frustrating in app purchases

I bought a bundle, and immediately when it downloaded, the app shut down. Now, every time I open it, Im prompted to return to the song purchase screen, and restore purchases. The bundle I purchased says I bought it, but when I click Im asked to pay again, and no amount of hitting restore will fix it. Looks like I wasted my money
