Sims medieval problem: WorldCastle.world

Hey!

I'm not new to installing torrents and doing the required stuff to make them work, but this error has made me nuts trying to find a solution.
I use the TSM-file as instructed and the game loads up normally and that, but when I try to create a new save (world?) and I type my new kingdom's name in, the game loads for like 1 second and after that a text comes up saying that a serious issue has come up with WorldCastle.world file and it suggests that I'd restart the application, and it doesn't crash, but lets me back on the screen where you can create a new kingdom. I've tried to search for an answer elsewhere, but it doesn't seem like there's one available anywhere. Someone said that his WorldCastle.world file was basically empty, so it didn't work, but mine shows to be 9,6mb or so I guess that should be the right file, I dunno whats going on.
Thanks.

Hello,

I'm not familiar with this error, but please try this:

1. Completely uninstall the game.
2. Restart your PC.
3. Reinstall the game, but do not apply the included crack!
4. Apply this fix: https://games4theworld.forumotion.com/t916-the-sims-medieval-ultimate-fix-should-fix-most-of-your-problems
5. See if it works now.
