Hey paasi,
What seems to be the problem? Without any details, I can't offer much assistance. However, just based off your output log, looks like you just need to verify your game cache. In your Steam Library, right click Pillars of Eternity > Properties > Local Files > Verify Integrity of Game Cache.
If that doesn't resolve your issue, please upload a save file and explain in detail, what the problem is.
Thanks a bunch!
