Been a while again - went to the Netherlands for the Nijmegen marches and went on hollyday.
Got my pc up and running again. The mission starts fine after installing the files mentioned earlier.
Yesterday evening when I wanted to play the last few minutes of the mission, I couldn't start up the pc. The power supply seems to be dead!
Wasn't much hope anyway. I had lost must of my antiarmour units, having spend all of their dragon missiles whithout destroying a single enemy vehicle
