I've tried this:
- Unninstalled every Redistributable and tried to run it again.
- Reinstalled the game.
- Used the Intel tool to verify if my cpu drivers were up to date.
- Cheked for windows updates.
- Closed every background application before trying to run Gladius, with the help of the task manager.
- Tried to start the game with Windows antivirus disabled.
- Also, tried dissabling every DLC I bought before starting the game.
Saludos!
