New downloaded levels will not run - explain to user why
|||Nikki and the Robots||
A 0.4 player can't play some 0.5 levels etc. The error message (any error message?) that comes from an error when loading a level should suggest that the player should try updating their game using the 'updater' in the main menu or by downloading the latest version from joyridelabs.de.
This text would probably have to be changed for when the game is included in distribution systems like App Store, Debian/Ubuntu repositories, etc.
