I can't play blockland because whenever I open Blockland up it closes after a few seconds. I don't know why though.
The day that it happened, my mother told me about a virus she had. It was a virus that closes any application she opened and shut down all her virus protection.
It got to her by her downloading it. She has a Gmail account and had set google to find her anti-virus stuff. Once she clicked it avast! (her anti-virus software) yelled at her not to download it, but she did anyway.
My mom also said that viruses can come from downloading addons too. I usually download from the RTB Mod Manager, so that isn't the problem. I used to use avast! too, but I usually use Spybot - S&D. As I type I'm running a scan, but if you can tell me what the hell is going on, much abliged man. I CAN'T PLAY BLOCKLAND!
