Game can not be saved

[fsx]

Hi!
Playing the game since release.
Some minor issues found, but not strange. It was allways playable.
But now, no chance to save the game. I tried on two different installations (without / with hotfix, no Steam) and also with quicksave (F5).

Load the savegame, press "end turn" and after the AI turn I miss the window with primary and secondary objectives. I am able to move my units, but I am not able to save a game.
I play with german language.
Savegame attached.

Edit: output.log added

Hi,

i Had the same problem since yesterday evening. I tried german and english versions. Both do the same. After Round 17 in Guadalcanal i can not save but play the next round and then the games stops. Can't select anything and the KI also does nothing.
