[BNW] Where did they go?

[Patrick Doyle]

I recently cleared out the cache file and now my default civs don't show up on the Ymaemp map anymore? I have reinstalled Civ 5, reset the map, reinstalled Civ 5 the second time but still nothing? This means no Dido, Theodora, Harold, Bismark etc etc....Please help

Is there a way to reset the whole game or do I need to install a patch? Please I am an old man and would like to play this game again before I pass on to the great Civ map in the sky....
