Ok, not sure what the problem is then... If I try to launch my modpack with Technic the launch because black when I click it... and under the modpack listing (on the left) appears the word "Loading...". Only thing the console says is "Valid:" (nothing after that)... But if I launch my modpack in MultMC5(beta, where I test updates to the modpack before adding it to the launcher) I can startup and login to my server with no problems.
As a side note: I have changed nothing in Technic, and it has been working fine all weekend.
Ignore the really bad icon, my friend made it as a joke, and to get back at him I used it... and have been using it for almost 6 months now .
