Actually, those maps (at least, the ones that i'm using now) have a fair amount of buildings, with huge cities and some military sites (airbases don't have control tower, hangars and etc) , but they are placed by software, so, cities are somewhat ugly, and military bases are a mess.
I'm at my work by now, so i'm unable to give a report of the error itself, but when i arrive at my home, i'll give some more details abou the error.

Thanks for the reply.

Hello, could you guys help me index some PMC Terrains? Especially PMC Balkans Montenegro. I tried to do according to the tutorial, but every time I tried it, he gave me an error saying that I could not index the map. I opened the map with the DRWP and it did not find any error.

Please, help-me find what is wrong, i really whant to create some air campaigns on those gigantic maps!
