I downloaded the feed the beast launcher and i was about to create a profile with my Minecraft information (username/password) and it keeps saying invalid username or password. But its all the same from my Minecraft account.
Feed the beast won't let me create a profile?

There's really nothing you can do if you know that the info is right. Try reinstalling or copying and pasting the info from your minecraft login to Feed the beast.
