I recently did some housework on my iPad 1. At the end I noticed that one of the apps I had bought had disappeared. I went to the app store and the particular app had 'install' beside it. When I pressed install I was taken to the iPad and it started loading but halfway across, the whole thing disappeared. I went back to the app store and it said 'downloaded' and is greyed out. The app isn't on my Ipad so does anyone know how to get it back?
