Every single time I try launching the game I get an error saying "error code : -2147024809 (the parameter is incorrect.). Google searching has done nothing to fix it. Running in compatibility mode has done nothing to fix it.Reinstalling has done nothing to fix it. My firewall is not stopping the game from starting and I used to be able to play this game just fine on this computer. Any ideas would be greatly appreciated. Thanks!!
Make sure to run it as admin as well as compatibility. And change around the compatibility mode till you get one that works.
