Okay so as the title says, i am unable to join any minecraft server, no matter what i do it doesn't connect. It shows on my server list that they're are people in the server. I just cannot join. i get a bunch of different errors depending on what server i'm trying to join. I either get "authentication to minecraft.net failed" or "failed to verify user name" or "error occurred while contacting login servers. are they down" and loads more that i cannot remember right now. I am using a Hp laptop running windows 8 64 bit. I used to use a Cracked client such as Mineshafter and Team Extreme. I've updated to the most recent Java. uninstalled minecraft and re-installed. I even contacted Mojang 1 month ago and still no reply. I am kinda mad that i threw $27 down the hole. If any one could help me out, it would be greatly appreciated.
