Well, since I didn't do any uninstalls prior to this one, there would be no duplicate files. Aside from a couple of disconnects, this is the first error I have had to deal with since installing the game. The 216 error didn't pop up until after the update (which would lead one to believe that the update caused the error) at which point I did my first unintall/reinstall of the game. Which seems to have fixed it since I can now log in.
