I already read the thread about the bug for the previous version of the dlc/game (mq10a could not be started).
I had that error the first time, then always at the end of the dialogue and quest the game loads and start from start.... (level 1 home sweet home).
I tried everythinh, start from an older savegame, disable vsync, change settings, uninstal and reinstall game but nothing changes.
Also the console command "setstage mq10a 5" sends me at lvl 1 home sweet home (game start).
Please help...
