So fixed?
I have no idea what causes it, and the solutions I have in the article are the only things that might work

Last solution for this I have that usually works. Go to your appdata/roaming folder and delete the ftblauncher folder. Rerun your launcher (be sure it is in a folder on your desktop or in c:/ftb or this solution won't fix anything.)
