pixel_player55452724 This seems to be caused by the game not being able to load dynamic content, to wit the regions. Normally the game caches that, but if you clear the cache, reinstall, or -- as in this case -- there's an upgrade, that's gone, and has to be reloaded.
But, I hear you say, my network connection's fine, sure, didn't I just download the game update, and connect to the server in the first place. Yup, but for some reason the dynamic loading thingie works differently, and can fail even when other net stuff seems fine. I suggest checking for any sort of VPN, proxy, etc, and trying again on a different network if at all possible.
