What can I do if I start Chathouse 3D and get a black screen?
Visit the Microsoft link http://www.microsoft.com/en-us/download/details.aspx?id=8109 and download the full version of DirectX 9c.
Please Note: Even if you have a newer version of DirectX already installed on your PC, you should install the FULL version of DirectX 9c. After you have downloaded the package, you have to extract the files into a folder on your computer and then run DXSetup.exe to complete the installation process. Now you have to start the Chathouse 3D game again.
