I never had this error code either until after Beta, too! That's what's annoying me the most. I even uninstalled everything I had installed to my PC after the date it started messing up, in a last-ditch effort to solve this problem. No dice.
And yeah, it seems like SE has a nice list of people who are dealing with similar issues but has not provided any answers yet. I just want to know if I can solve this issue on my end or if it may be addressed in a patch. :\
