The patch isn't the cause of the crash you are getting. For further troubleshooting, I'd recommend creating your own thread so we can better assist you.
Thank you everyone for your replies.
My first thought is when you were disconnected, you were placed somewhere that is more difficult for your connection to reach, but not impossible. Your character may have been put into an area behind a port that your router has blocked, so the first thing may want to try is opening all the ports the game requires (If you have access to a different router/connection, such as at a friend's house, you may find it easier to log in and move your character).
Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened/forwarded/triggered:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
Your ISP may forward these ports for you.*
If this does not solve the issue, try some of the following options:
Make sure your Anti-virus/Firewall has the appropriate exceptions for the game.
Use a wired connection as opposed to wireless.
Reset your router by turning it off, then back on.
Open the Internet Explorer browser, open the "Tools", go to "Internet Options" and adjust the following settings:
