Hi there.

I have the same problem as you have since today. A few hours ago everything worked fine, but now it doesn't work any more. My girlfriend has the same problem. We play with a private modpack only me and a few friends use. As of now at least two of my friends can still load the pack.

I have turned on the console and this is the error that shows up:

[B#310]  [18:36:30] [main/ERROR] [LaunchWrapper]: Unable to launch

Do I understand correctly that an update for the technic launcher launched today? Might this be causing the issues for us? I would appreciate any help in this matter.

EDIT: We have also tried fully reinstalling the modpack and the launcher (deleting the folder the launcher uses as well as the launcher itself).

try to launch your modpack with the 0.7.9e launcher

Update: My game seems to be launching fine again after the latest technic update. Thanks for the help!
