I last played ESO soon before the Imperial City update was released, but a move from the US to the UK prompted me to take a break from the game. After updating my game, I'm finding that any attempt to log into any character that isn't freshly made and still in Coldharbour results in one of the following two errors:
Unable to connect to game server...
An error has occurred. Please wait a few minutes and log in again.
I haven't changed anything as far as my installation goes since before my break, so I can't think of what could be causing this. I haven't reinstalled Windows or the game, nor have I changed anything with my antivirus (Avast! Premier). As stated before, I'm able to create new characters, though I'm unable to complete the tutorial as loading the starting zone fails at the end every time, disconnecting me from the game. I've tried several different characters in different zones and factions with no luck.
I've even tried disabling real-time protection within Avast to see if it could be the culprit, though even that doesn't seem to make a difference.
I haven't tried uninstalling and reinstalling the game, as it'd be a major inconvenience given how large the game is.
Any help would be appreciated.
