[JG3_VonHahn]

In MAPS I only have the all.ini, were all maps are listed, and some other text documents, but not for the maps themselves like berlin, crimea and so on.
In MAPS in the Berlin Folder I have only a modified load.ini

but I could think your problem is a defect load.ini, if you delet your Berlin Folder in MAPS, the game should use its own, not modded (and so extracted) Version and all should work properly.

Try this out
