As some of you may have noticed when trying to play this game again or even for the first time, when it prompts you to press 'B' to open spellbook, you realize it does not work.

I do not know the reason why this happens, but somehow this solution fixed this problem for me on MS Windows 10.

Just follow the following steps:
1. Go to settings;
2. Select Time & Language;
3. Select Language;
4. Select Administrative Language Settings;
5. Change Region to: English (United States);
6. Turn false (uncheck) this checkbox: "Beta: Use Unicode UTF-8 for worldwide language support";

I hope this helped you.
