Windows .exe Invalid Username or Password

[Sidern]

Okay, I am having serious issues with this and I have now sent in a support ticket, yet I shall post here as well with the hopes that one of you will know what to do.

I've been playing the Direwolf20 pack on my FTB launcher [v1.3.3] for about 2 weeks with my legitimate account that I've played vanilla minecraft on for about 2 years now, yet all of a sudden it keeps popping up with "Invalid Username or Password", the same username and password that works perfectly fine on the vanilla MC launcher.

I've tried reinstalling the launcher, changing JVM arguments, deleting the launcherlogs text, edited/removed and replaced my username and password but nothing works.

Does anybody know what could be causing this? Because I've spent 2 hours googling and searching through these forums to no avail.

have you Migrated your account?
if you have, you need to use the EMAIL ADDRESS you signed up with to login, not your username

I have the exact same problems.
Yes, it's migrated - a long time ago actually.
Yes, I log in with email.
NO, it does not work.

strange, i only just migrated my account yesterday, and it works fine for me.
you could try changing your password on minecraft.net, see if that makes a difference?
i notice from Here that mojangs legacy minecraft session servers are down just now though

 

[Sidern]

I've done that. I've been using Username AND Email Address, NOTHING works here.
My account is post November 2012, so I've always been on the Email username anyway, I've reinstalled etcetra as well, many times.

Plus when the legacy servers were down my friends could still get past the launch page whilst I could not, they just couldn't access the server we were using.[DOUBLEPOST=1390229351][/DOUBLEPOST]And I also sent in a ticket 13 hours ago with no response yet, this is getting frustrating.

Nice, we buy a game and cant play

After i try some times double clicking the modpack, it works

 

[JamiePhonic]

sorry, but i cant tell you weather is the launcher or something on mojangs end. i migrated my account and can play no problem.

Presently Gaz is the only consistently active person on the help desk, and he is at university. Also, it's a volunteer gig, so he doesn't get paid. His school work is significantly more important than working the help desk.
