Hi all!

I've had my share of problems now when (FINALLY!!!) being able to play this amazing game once again since my childhood. Most problems such as effects has been solvable through re-installing in steam and such. But, there is still two things that I still can't be able to fix...

1.
Missing boy. I've killed the vampire and freed the boy. I've completed the quest with the knight but still the quest "missing boy" that I got from the random appearing lady is still there. How can I fix that? Why haven't I completed this quest ? :S

2.
Georges murder. I've talked to the vampire in verdistis about the murder and got "Speak to mardanius about georges murder" in my quest log. Bet when talking to mardanius I can't speak wit hhim about it. Again, what's wrong? How can I fix this? I've already saved past this unfortunately so is there a way?
