Hi @Ghosteu

There are sound errors in the log:

warning: Unknown DirectSound speaker configuration 8. Defaulting to Stereo. warning: SND: XACT3DApply failed. Invalid arg

To fix this, please follow this guide:

If your game don't crash but freeze (sim stops, but UI is still working)
Please try a game and don't let the AI play the UEF faction.

[Edit] Only if the game freeze, try/test the AI-Uveso mod (there you can also use the UEF faction for AI)
