I have a problem since mission 12 in The Shattered Kingdom.
I tried to run it with compatibility with XP or as an administrator.
Also moved it outside Program Files.
Any ideas how to fix this?

( I had similar issues, just on the startup - another User (Kobi-K) had helped me out by providing the following link (Copied/pasted entire response)
I've played up to TSK 14 without an issue )

"I don't have the game but from searching on it, it says that the game has problems running on modern PCs.
However, there is a mod called KaM Remake that enables you to run the game on modern PCs even on
wide screen resolutions.

You can download it from Mod DB:
