I originally purchased the white noise program for my sprint Evo. It has always worked fine I have now moved to an HTC vivid on AT&T. First I found at white noise would mysteriously started self without being prompted. Now I find that my favorite scene, beach toys, pulls the wrong sound for it. It has gone back to using the sound that comes with the free version rather than the sound with the paid version. I uninstalled and reinstalled and the soundest reset but then in the middle of the night it's suddenly switched back to the free sound. I'm not sure what to do from here.
