Ever since the patch, I've been unable to run the game. When I start up I get the "start screen", with the choices to update, launch etc... But once I click play, the start-screen closes itself and I recieve an error message that reads "Original disc could not be found or authenticated" - Is there anything I can do to fix this?

 

Thank you!

Did you finish the game without any major problems or bugs, before the patch was released? If so, unistall the game, reinstall and play without the patch.

 

I never experienced any bugs with the original version of the game, and when I installed the game problems started appearing all over the place.

 

Just my 2 cents.
