Error on trying to connect to the minecraft servers

I know that I have my email and password correct because I can log into the paid minecraft launcher just fine. Here's the log thing:

I can log into the classicube servers just fine with no problems at all.

I'm experiencing this issue as well. Here is the error log:

Have you tried logging into minecraft.net first than logged into the client? Mojang is trying their best to remove anything related to classic on their website, and they changed the website ever so slightly each time making a bug in our launcher.

I resolved this by loggin into minecraft.net first. That did work. Maybe the catch block for this should have it added in that you need to do this.
