Hello,
after our redesign last year we don't update our gfx-pack files and this game feature was out of date.
Now we have updated our files and the game. You can now download and set up the path in your ingame settings to load the images from your local computer or some other source.
If you have questions or problems don't hesitate to contact us in our ingame chat.

Important: You cant use the GFX-Pack if you use the Opera web browser. Thats a security feature of Opera!
Good profit!
Your IT-team
