I'm trying to download the World of Minecraft client pack... thing, but everything I do it, this message comes up (refer to title). I go to the Minecraft page to download the .jar, but then this happens. There may already be a thread about this, but I'm new here, so I don't know exactly how to navigate anything.
So yeah, if anyone could help me, I'd appreciate it. I google'd, but couldn't understand what anyone was saying.
