Are you playing from a physical copy of the game or a digital download? If download, did you download the game using a wired or wireless connection? Have you attempted deleting the game, including all associated game utility files, and reinstalling it? If disc, have you checked if there is any damage to the disc?
I am playing from a rented hard copy. I downloaded via my wireless network. The disk is pristine. I have deleted and reinstalled twice, resulting in the same error every time. Multiplayer works fine, but trying to run the campaign is useless. It looks like I'm not the only one that is having this issue.
I can tell you that other users are experiencing similar issues, you are not alone, and we will assist you as best we can. I don't quite understand what you mean. You have a rented hard copy, but you also have the digital download? Have you tried disconnecting from the internet while attempting to play. Try unplugging the ethernet cable, as well as disabling the wireless connections. If that doesn't work, can you delete the game one more time, then you can try downloading a few free game demos, movies, and music to force the game install to reach a different section of your harddrive. Let me know if that addresses your issues.
Sorry, I am playing on a hardcopy. I should have said I got the few patches that have been released through autodownload. The errors are now happening on both multiplayer and campaign mode. I 'll have to try uplugging the internet, but then I won't be able to play multiplayer. Soooo.....
My deepest apologies, are you still experiencing the same issues? Did you try downloading a few free games, demos, and movies, before reinstalling the game on your console?
