Fixing crash on startup and endless loading screen

Crashing on startup

Some game's files might be missing, just download them there[drive.google.com] (google drive link) and put it in your game's folder. (don't be scared, there are no malicious .exe or .dll files, just an .zip archive containing three .p3d files)

Endless loading screen

If you've got fixed crashing on startup, you might have a problem when your game gets stuck on loading screen. There's a fix for this one too: download audio_german.rcf file (1.9gb file compressed to 1.2gb, get it from here[drive.google.com] or here[mega.nz]) and extract it to your game's folder (same as two files before).

THANK YOU, I've been trying to play it since I bought it on 2022 and this fix worked on my Steam Deck but sadly it didn't on my main PC

Thanks a lot! Finally I'll be able to play this one. To think it was just some missing files...

Over 7 years after the OP, I have to thank you and you alone! So many "fixes" on the internet, yet your zip with a couple of missing files did the trick. Thanks!

This fix did not work for me but the one in this video did. Had to reduce the CPU nodes from 15 to 11. Video link is timestamped to the start of the fix explanation. Hope this helps.
