Did you recently download the game or did this suddenly happen and it's worked fine before?
Did you recently install anything prior to this error?
More information always helps, always.
Since we have no way of knowing what 0xdb0399b9 is, it's going to take some testing to figure it out. It could be something as simple as a corrupted download, out of date drivers or damaged system files.
Awaiting response before I waste either of our time throwing out possible solutions.
