I just got the FTB launcher (note massive mod noob here) and I did all the requirements and type in my minecraft username and password. It said every time I tried that one of the 2 are invalid. Someone please help me understand what to do to fix this problem. I would very much appreciate it!
;)

You may want to contact Mojang. You may have fallen victim to an account compromise.

First step when username/password doesn't work is help.mojang.com and check if authentication services are down.

If all servers are up and green:
Go to www.minecraft.net and attempt to log into the website.

If you cannot log in:
You may have had your account stolen by somebody who guessed your password. Go back to help.mojang.com and contact support.

If you can log in:
Completely remove your Minecraft and launcher installations (including the stuff in %appdata%). Redownload the launcher and try again.
And/Or:
Change your password via the website. Some users recently had login troubles and were able to resolve them by changing their passwords.

Well, I found I'd get invalid username/password errors randomly, and when I look into the profile section of the ftb launcher, my password is about 30-40 characters long. It added lots of random characters onto the end of my password, which then made it invalid obviously

Sorry for not responding to all of you sooner! I just deleted the pack and re downloaded it. My FTB pack works now! Thanks for everyone that helped![DOUBLEPOST=1386632263][/DOUBLEPOST]

I don't know if your talking to me or the idiot that told me to use a cracked launcher. His comment is gone now so I don't know if you were responding to me or the guy that gave me really bad advice.

Welcome. I've noticed that sometimes the password gets corrupted. Since it is asterisked (*) out and unreadable I can only assume that, as it appears to either double or gain a lot of extra characters in it. Not sure of the cause or how often it happens in the new launcher version. The next time it happens check the profile and see if it looks like your password got corrupted.
