s_instance != NULL

Age of Conan does not start anymore…

Anybody have an idea??

Did you try to repair the data by clicking the repair button in the launcher? This might fix it but I am not sure about that, I never saw this error before.
Since it has something to do with the soundengine, maybe try to update your soundcard driver?

Moved thread to support.
