FIFA 14 not installing on iOS 7 ipad 3

I started downloading FIFA 14. According to their app description the entire size is somewhere around 1.3 GB. After completing half the download my internet was causing a problem. I switched to my phone's 3G internet to complete rest of the download. After using almost a GB the progress is stuck at the installing screen. Do you think I should delete the installation process and start the app download all over again. I checked my bandwidth with 3G watchdog as well as for my computer and looks like I downloaded more than 2.1 GB of stuff. Please help.
