end turn button stuck

[Pugalshish 1]

I was playing a game of Age of History 2 and tried to hit the "end turn" button, but it didn't work. Then, I tried using the space button, but that also didn't work. would anyone know what I can do?

In the menu of AOH2, Go to new game, start a new game, then press space. After that, go back to the menu and load the saved game, pressing space should work again.
