Hi DraygamingYT,
Thanks for contacting ZARP. We've just taken a look into this issue for you and can see that your purchase of ZARP VIP was successful, all you need to do now is link your Steam profile that you use to play on our servers to your ZARP account. Don't worry it's very easy to do. Firstly make sure you're logged into the ZARP website then navigate to this page:
zarpgaming.com/index.php/zarp-vip and follow the instructions to Sign-In with Steam.
After you've linked your account simply re-connect to the server and your upgrades will start working in-game automatically.
Please do let us know if you require any further assistance.
Thanks for supporting ZARP!
ZARP Administration Team
