Error 000c:0000 means there has been an error because of an unsupported graphics card. This could be because your computer doesn't meet the system requirements for your game or that DirectX needs to be updated or is corrupted.
Check that your system meets the system requirements.
You can use the En Masse Diagnostic Tool in the En Masse Launcher to check what your system has and if it meets our system requirements. You can also manually check:
- TERA System Requirements on PC
- Closers System Requirements
- System Requirements for Stranger Things 3: The Game
In TERA you might get this error message if your video does not support 3D acceleration for the Unreal 3 engine.
If your copy of DirectX might be out of date or corrupted, you try downloading and installing DirectX again. Most of our games need DirectX 9.0c, which you can download and install directly from Microsoft.
