I have had a PatchManifestError 210 since Saturday, April 27. Have tried a few fixes provided by support, with no success. (On a separate note, have not heard back from them on my ticket in over 60 hours.) Have tried to uninstall and reinstall game, with no success either. Has anyone else had this problem and if so, how did you resolve it? I also use Steam. Any help you could provide would be greatly appreciated.
