Mad World Age of Darkness

I'm having trouble logging into the game on my main character. When I press start game, the loading is interrupted at about 74% or crash at 0% and I am taken back to character selection with a window like this [screen]

Perhaps this problem could have happened because my character was stuck on a quest and an error occurred. I killed the collector boss and I had a dialogue with the Libbie after the fight, she offered to go back to the camp and at that moment the lights went out in my house. When I tried to create a new character and start playing, everything worked fine. But I would like to continue play on my main character, is it possible to solve this problem somehow?
