Keep getting content errors

OK, I’m using Windows 7 w/ Google Chrome. Anyways, I start the game and everything’s black for a while. Then it connects me to the server and everything, but then it either gives me a content error and crashes, shows half the sky and crashes, or shows the chat then crashes. And sometimes it just crashes right away. I know a few people are getting the black screen thing, but I don’t know if it’s the same scenario.
