Help - EoC not saving

So I started playing EoC again, hoping to maybe complete it finally. Re-downloaded it from GoG, started playing. Saved the game first chance I got. But when it came to loading, the save wasn't listed. And if I go to save again, that's empty too. I don't know what's up. Any one know of a fix?

Wait, think I've sorted it.

I have encountered errors with the different executables for the game. If problems persist, let us know, we can probably help.

Can you tell us how you fixed it? It may be interesting for other gamers as well.

Me or Kain?

Kain

(When I hear that name, I always think of "Soul Reaver".)
