Alright here are my next solutions:
Delete the Game.
Make sure to you delete the Skunk Spray Love Folder at Appdata. Here is the path when you are using windows.
C:\Users\youruser\AppData\LocalLow\Markus\Skunk Spray Love
you can also get to Appdata when you write %appdata% in your windows search.
Delete the Skunk Spray Love Folder.
After that download a new version of the game and try it again.
