When I looked at snapshot 13w25b, I tried logging in with the new launcher, but the same launcher screen stayed the way it was, and didn't start Minecraft. Thank you.

This is an issue with the Mojang servers. You can check the status at http://help.mojang.com
If you can not log in and the status is green, I will reopen this ticket. However the timing leads me to believe this is your issue.
Please try again.
