Those crashes do only happen to me, on my computer where I'm using Discovery Launchpad. But for my brother, who is using only FLAM the account changes work well.
So I believe it is the launchpad that gives us this, fatal crashes. But also it might be a incompability between different programms. I can take a look over your programms, via teamviewer. Just add me in skype and we can try to solve your problem.
