--- Comment #6 from Bruno Jesus 00cpxxx@gmail.com 2011-09-28 14:30:02 CDT --- Can you confirm if this path exists: C:\users\korn\Gespeicherte Spiele
If it does not can you please create it and retry running the application? It looks like the saved games folder does not exist and that check makes the function returns error.
