Ok, I went through my steam account (purchased the game through steam) and clicked on the Crusader 3 game, and when I pressed to play a red triangle appeared. This was odd because I played on the game two days ago with no issue so I went on my paradox account that was linked to my steam because I also have the game stellaris (which I purchased through the same steam account) and I also notice that my game Crusader 3 does not show on my games on the Paradox website (i dont know if thats a problem but i just will mention it if it helps). I already tried to uninstall and reinstall the game twice and also verified the game files. I also already unlinked and relinked my steam accont also twice.
