Windows .exe Invalid Salt

[Onikrex]

Hey guys, I recently rebuilt my computer, and downloaded FTB. I've got Launcher 1.2.7, and when I click "Launch" on ANY modpack, I just get "Invalid Salt Version" and it asks if I'd like to play offline. Any idea why? I can't download any of the modpacks to be able to play them.

I've seen a few dozen reports of this on the help desk. Only 1 person has responded to me past the troubleshooting steps. That 1 person stopped responding after I told him to change his MC password.
This error didn't occur until after Mojang had that issue with their servers a few weeks ago (where everything was down for nearly the entire weekend, on and off the whole time)

I actually fixed it, I had to type in my email address, whereas I'd normally type in my profile name.

You should do that anyway if you have a merged account.

Do you mind me linking this thread/issue on the help desk somewhere?

I've never had to do it for FTB before, but it works fine now. And not at all, go ahead! c:
