Hi Exrobite!
Inorder for your VIP to work with the new system you need to have linked your steam account to your forums account. You can do that by going to this page and following the instructions found near the bottom.
zarpgaming.com/index.php/zarp-vip This will ONLY work if you have purchased VIP in the past, if you've only had VIP due to being that rank you will have to actually purchase it.
