Hello, I've seen you deal with a lot of problems like this. Firstly my Technic said that it couldn't reach the authserver.mojang.net when I tried to log in but I messed around and reinstalled Minecraft and fixed that, but now it will only play Technic offline and when I tried to update my Tekkit modpack to the latest version it doesn't show any mod packs on my launcher. I have an i5 windows 8 laptop. I have got the latest version of Java and have re-installed it a few times. I have re-installed .Technic and Technic a few times. This has been happening since the 11th of April. I don't have Norton and my anti-virus is disabled. Please help.
