===== The thriXXX software crashes when starting, or the PC hangs completely! =====

In most of the cases crashes (esp. of the whole PC) are caused by older or incompatible graphic adapters.
You can try switching to Direct X:

  - Start the Game
  - In the login window click on 'Options'
  - In the box 'Renderer Type' click on 'Direct X', then click on 'Save'
  - Try starting the software again.

Additionally we strongly recommend that you download and install the latest graphic drivers (including [[..:open_g_l|OpenGL]] support!) for your graphics adapter. You find some links for graphics drivers [[..:graphics_drivers|here]].
