Error not possible to start the game

hi,
bought the game today, but i am not able to start the game. (steam version)
Deleted all local files (includes the complete files manually)
Tried to reinstall 3 Times, didn´t help.
Tried to fix via Steam checking local data on errors, steam recognized that there was something missing/incomplete downloaded about 80 new files, error was still the same.
Got everytime the same report/traceback

Help plz!!!


I'm sorry, but an uncaught exception occurred.



After initialization, but before game start.

Exception: DirectSoundCreate: Mixing buffer was lost
