Sorry to bring this up again but still since day 1 I have been having this problem, updated it this evening and still An error has occurred. Check your network connectivity still comes up. I do not understand, and yes Ive tried the game spy method but that has not worked any other suggestions?

what is the game spy method, and how did you update without logging into the game?

I amhaving smae issue since demo, please fix.

In my case, it's always when I have internet connection sharing on (e.g. sharing my ethernet with my wifi card so that I can broadcast with wifi). Turning it off works for me. Might work for you...

Still doesn't make **** for sense, though.
