Can't log in; keeps saying password is incorrect

[Sneakyy]

When trying to log in for online play, it keeps saying the password I typed is incorrect even though I know it isn't. I made a new account and tried logging in with that, but even the new account that I definitely had not forgotten the password for didn't work. I am on version 1.2.2 (it won't let me select it, it only goes up to 1.1.8). I wasn't sure what priority to set it as, since technically it doesn't stop you from beating the game, but it's locking me out of online altogether, so...
