When i try to open a pack made by the FTB team that is for MC 1.4, and it just greys out the edit, and launch buttons, as well as the profile selection expander:

View attachment 2823

it just sits at this screen and does nothing, even if i leave it for a while.



Another problem is that I can only open the retro ssp pack right after i log in to the computer, otherwise it closes right at the mojang screen

Does anyone have a solution for me?

Thank you for the information about 1.4 packs, although no restarting is fixing this problem, and has been happening for over a week.
Do you have any ideas about the ftb retro ssp problem

This problem might be totally unrelated but on my system I was having the same/similar problem. I figured out I need to run the launcher as administrator and then it started launching packs properly.

Are you referring to the problem with retro ssp orthe other problem. The first problem I have solved, the computer was just being stupidly slow
