Uh...I...don't even know :/Launcher Version:
Whatever the latest one isModpack:
All of them technicallyModpack Version:
The problem is with the launcher. One of the users I have installed has such a long name, it COVERS the delete profile button. Because of this, I cannot access my account because it doesn't let me delete the long user named profile. I tried reinstalled the pack, deleting everything tagged as FTB, and reinstalled java; nothing worked. I need this fixed soon because at the moment, it is impossible to log in to play.
