I retried several times and suddenly, the game didn't crash anymore. I get the "push any key" screen to go to the main menu, I push "continue" and then it loads to 100% and returns to the "push any key menu". I can repush a key , see the menu again and choose "continue" or "load game" again and it goes on like this ad eternum.

I can create a new game with Karlach as origin character. It goes well until I find the first rune slate in the first nautiloid room. It doesn't respond. Right click on it and I get the "read" menu item, active. But clicking does nothing. I can pick it up though, but not read.

Anyway, I would love to continue my existing Karlagh game.
