McKenzieM98 Does the game work in offline mode? And does it help to disable Norton entirely? I'm not suggesting you get rid of it in general, but a quick test should be safe as long as you don't do anything else with your computer at the same time. Just disable Norton, repair the game, and see what happens.
If that doesn't help, please list the full path to your user folder, where your saves are (and the content folder as well). Right-click the folder and select Properties > General to view the Location. You can write [username] instead of your actual username if you want, but please leave the rest intact.
TedDizzle Same goes for you if you've tried everything else in this thread AND you have exactly the same error. If your error is different, please post a screenshot.
