Mine broke too, however if you uninstall it from the iPad, then push it back by syncing in iTunes, it will start updating again.
I do not think you will be able to get your money back. It would be like going to Microsoft asking for your money back for Windows 98 because you upgraded to Windows 7 and Windows 98 is now end-of-life. Just doesn't happen. Just delete it from the iPad and reinstall it from iTunes.
