i have not downloaded it yet however there is a way to make all maps work as had a problem with a brazil only version.

install the exe file, run the program once and it will show no maps loaded. go into the root menu and delete the "save" folder, reboot your system and try it again. if you have different map folders eg map_ot,map_ta make sure there is a default basic map file in it, like a base file or just copy fbl in each folder (can be same as default so if you use tt use it in all folder or here in all folders). and see if that works.
