Thanks for an answear JWideman ! Though I ticked "enable the scenario" and picked France I've started in South America

Maybe it has something to do with me playing BNW DLC but it shouldn't be the case. I didn't tried to enable all 22 civ's that was supposed to be in that map so maybe that's the case. The map is called "The Greatest Earth Map" downloaded here from the CFC download section and it has TSL tag. So what do You think ? Should I manually enable the civ's that supposed to be on that map ?
Aha !

... Now I've checked it's preciseley "Greatest_Earth_BNW.Civ5Map" - I've put the file in the main instalation/Assets/Maps folder ... hmm maybe I should put it in My games/Civ 5/maps folder for it to work but I think it's highly unprobable that's the case. I feel stumped
