Oh, I just made a post about this too! I have the same issue where all the text is tie dye colors. Very pretty, but not playable like that. I posted a pic in my post. Sorry yours is acting like that too.
I was having issues getting logged in. Resetting my password, having the password reset take. I got the same message as @Cynder.2509 which is what prompted me to change my password. I finally got logged in and have gotten the message pop-up about the game client being unable to connect to the log in servers. Code=42:1053:9001:4479:101
