I'am currently working on this. I have two PC's & so far I bought H1Z1 3 times. If you get HWID banned, it bans your MOBO, so in order to play the game again, you have to get a new motherboard or a new PC. I went on my labtop without changing my IP or ANYTHING then I bought H1Z1 & I was able to play. I then got on my other computer that is HWID banned & used a VPN, changed my Hardware Serial Number, logged into the un-banned steam account & got banned instantly. So either get a new computer or a new MOBO.
