Trying to log into single player or multi-player 1.7 versions causes crash

What I expected to happen was...:
Logged into my multiplayer at MCProHosting yesterday with no problem

What actually happened was...:
Crashes immediately after picking a multiplayer. Unable to load any multiplayer minecraft games. Contacted MCProhosting, they couldn't fix. Unable to log into my own, and minigames on playmindcrack. Only thing I could log into was the latest snapshot profile I had (which runs very poorly) Only thing different between yesterday today was trying the latest snapshot in single player, and there was a new launcher downloaded automatically today?

Here is the crash report:
