I have installed FlightGear, a flight simulator. Some of the game's main files have been tampered with by a third-party app and the game no longer works.
It's a very big download and as I'm on a very limited bandwidth connection, I would like to know if there is a way to re-install the game from the installation files that Elementary OS's Software Center originally downloaded - instead of having to uninstall it and then re-download and re-install it all over again?
