I tried the solution but it did not.
Can you help?
Well by what you're saying, the problem is that you're missing DirectX9.0c so the solution is this
3. Error: Invisible Chars/NPCs or error message: Missing d3dx9_42.dll file
- Install DirectX 9.0c by running dxwebsetup.exe file located in EPW/element/ directory
Make sure that the game is not running while you're doing this.
