Minecraft Forums

So was working fine yesterday but when I went to play today the launcher is stuck on the Play Offline button, how do I get it to switch to the Play Button.

Windows 7 Home Premium
amd Athlon II
4GB Ram
64-bit operating system
Have the latest verison of Minecraft
And the latest version of Java
No mods or enhancements, just plain vanilla minecraft

Here is the Development Console (which I don't get ^_^)

Also tried to restart my computer, didn't work.
Tried to login with the old Launcher and gives me the error: Can't Connect To Minecraft.net
