Did you share it?
I'm trying to ask him for a new key. Lets cross our fingers he will give me one.
Hah good luck on that he could care less if he de-activated your key. He just wants you to buy the game again.
If he wanted to make money like that he could just disable everyones key and say it was an accident.
No, not at all. It's only been installed to computers inside my own house.
That may be your probelm.
A: One key can be used for any number of people as long as they are using the same name and are at the same IP address (ie in the same house). Clan tags can be used to distinguish different people with the same name.
You know, sometimes the game just randomly says "Invalid Key;" try restarting Blockland, or even your computer.
