So i tried to load up Tekkit yesterday after a friend invited me to a server he was running. I selected Tekkit and hit play. The files loaded for about five or six minutes then the launcher disappeared then popped up again as if nothing had happened. I tried re-installing technic pack, i tried uninstalling my virus protection and i allowed technic pack to work with my firewall and it's still not working can anyone help me please?
