Invalid Credentials (Won't Log In)

[Cube_]

Launcher Version: Latest (325)

Operating System: Windows 7

Java Version: Version 6 Update 33

Antivirus Program:

Description of Problem:

I can launch the screen where you log in, but when I try to type in my Minecraft username and password, it shows a pop-up saying, "Invalid Credentials." Can anyone explain this? I can log into my regular vanilla Minecraft with identical information. Please help.

Thanks,
