Why it shows a blank map after loading? And where's the collection?

I am new to CIM 2 and desperately want to get this scenario to work. As cimexchange has folded I cant download it there. My understanding is that the map probably needs to be located in my Users\Appdata\LocalLow\Colossal Order\CIM 2\Maps directory.. tried that but I still get a blank landscape. Do I need to edit and rename the file? ... Thanks

I don't like CimExchange, so I'll pass on this scenario. Pity, it looked good as well.

Probably still not, and it probably never will. Go for the manual installation.

Is this now fixed in Steam Exchange?

Unsubscribe and go for the manual installation - http://www.cimexchange.com/files/file/676-reeve-delta-scenario/

the scenario works but there are no builings, only landscape.

Hermoso mapa, te felicito!
