I found this on the Forum : https://forum.il2sturmovik.com/topic/35771-how-to-save-a-broken-career-automission-start-failed-mission-save-error-statsubmitstatfailed/ It's explain How to modify an existing campaign and repaired the broken save ! I'll try this.. Edit : It's work for me, the cutscene on 1942.12.10 freeze my carrer. I set the date to 1942.12.11 and the mission start well.
I had a similar problem, my carrer didn't not start since i past on the winter section of the story. The cutscene was started and the game just freeze.. i restarted the game but the screen is freezing on "Please Wait". I have to kill the process manually. I Try Run as admin IL2.exe, Disable UAC.. I will try to run the game on Windowed mod
