The app was last updated back in May 2013. It's possible that it is no longer supported, since Windows Phone 8/8.1 has Instagram, and there are very few Windows Phone 7.x users still around. Unfortunately, you probably won't be able to use many apps in the near future, since Microsoft doesn't even support Windows Phone 7.x anymore.
