1.9 was recently released, right? I want to try it out, so I get to the launcher, click edit profile, and then change the version to Release 1.9. Then, I try to play single player, either making a new world or using an old one, but a split second after it loads, it crashes. The games just throws me out. It also happens on multiplayer! Next, I get a message at the bottom of the code that says, "Using incremental CMS is deprecated and will likely be removed in a future release." I just want to see the new stuff, but I don't know why it isn't working. Any suggestions/help?
