I was doing the PPQ when I got a random disconnect, booting me back to the title screen. There, I was unable to log back in, getting stuck in Log In screen. I closed the game and tried to boot it up again, but ever since I closed it I am getting the same error message. Even after restarting my PC I get the same error message. The error message reads "error code: -2147024809 (Falscher Parameter.)"
I in fact do. It was reccomended to me to run it in Compability Mode for Windows 7. My OS is Windows 10
I changed compability to Windows XP Service Pack 3, and the game worked again. Strange that suddenly the Windows 7 Compability stopped working when it had been working fine for a couple of days Regardless, thank you very much for your help, it works again!
