Also thanks to huxl, even if I did not need this work-around in the end.
I am very happy that I can play another Japanese campaign at last. My all time favourite five star game campaign still remains the East Wind, Rain campaign for PacGen, hopefully yours will be just as good, if not better.
I am playing at the hardest normal difficulty, I suppose it is the same as Field Marshall.
A few suggestions, though:
scen 1.
Victory conditions should be shown between the turns. Maybe it was intentional, but it was not clear for me what to do in the 1st scen. I managed to take all primary objectives in turn 8 only to see that the Russian counter-attack goes on. I realised that I have to hold all objectives until turns run out, but if I had known this before I would have chosen another tactic and I would have avoided a few uneccessary casualties. Anyway, I held all primary objectives while loosing a core light arty unit, and four aux units. Only out of curiosity I checked the victory conditions with the editor after the scen and realised I was well within the DV, not to mention MV. Again, if I had known it maybe I would have saved my core unit. Sorry, maybe I am a little bit crazy, but somehow I feel responsible for my virtual soldiers.

Other than that it is a very good first scen, it starts easy, and then it gets harder as the Russian bear awakens.
The new UI and icons are superb, my only small concern is the visibility of the artillery units. Maybe it is only because of my laptop monitor but I can hardly recognize their details because of their faint colour. Maybe some more saturation or a different colour would help. The basic colour of the light AT and arty units is also very similar to the colour of the Russian infantry uniform which is a bit confusing at times. However, I am not sure what coulour they used historically and if this is the right one than its ok.
