It really does seem to be a bit of a matter of luck whether it works right away, but I’ve found another method that seems to work better (starting from step 2 in my description below):
- After setting the game back to your native language, copy the English voen.toc file (do not rename it!) directly into both loc folders.
- Delete the original vode.toc files (or the one for your language) from both folders so that only de.toc (or the one for your language) and voen.toc remain.
- Start the game and go into the campaign.
- A warning message should appear prompting you to repair the game: Close the game and click on Repair in the error message.
- Once the repair is complete, start the game again.
Now the game should use English voices and your native text. It’s best to test it directly in the campaign.
