Q. My Launcher starts up but there are no packs!
A. Your Launcher might not be able to connect to the net. Before you open it, try right clicking, and on the drop down menu select "run as admin". This is reported to have bypassed this issue. (Windows only)
Next time, follow the advice given.
If this doesn't solve it then make a proper bug report in Technic Launcher Bug section. And read the stickies.
