Hi bobtheteddybear,
We have taken a look into this issue for you. You have not yet linked your Steam Account which enables your ZARP VIP upgrade across all our servers. Once you do this your upgrades will start working instantly. You can link your account by clicking onto the ZARP VIP tab at the top of the site, and then pressing the Sign In With Steam button. (See here if you still need help:
