Well I don't know what has been wrong yesterday but today it has worked easily.
DLC 39 installed patch 1.04 and then everything goes fast. DLC 39 followed by DLC 40, start program, go to war.
well, I am another guy from Germany who want to say hello to the community. I also played Panzer General and I have been pleased to see that there is something new which could have the potential to be a worthy successor of the original PG.
