I'm afraid you can't. Here is why:
1. Funnelify Gold Templates Pack and Funnelify Platinum Templates Pack are only an up-sells or upgrades of Funnelify Ten and/or Funnelify Unlimited which adds 50 and 150 additional Full Page web templates inside your Funnelify builder.
2. Since Funnelify Gold Templates Pack and Funnelify Platinum Templates Pack are only up-sells or upgrades you must have Funnelify Ten or Funnelify Unlimited in your account first in order to buy Funnelify Gold Templates Pack or Funnelify Platinum Templates Pack.
3. Even if you buy Funnelify Gold Templates Pack or Funnelify Platinum Templates Pack without buying Funnelify Ten or Funnelify Unlimited you wouldn't be able to use Funnelify because Funnelify Gold Templates Pack and Funnelify Platinum Templates Pack are depended on the standard product. So, with only Funnelify Gold Templates Pack or Funnelify Platinum Templates Pack in your account you wouldn't be able to login.
Note: In case you bought Funnelify Gold Templates Pack or Funnelify Platinum Templates Pack without buying Funnelify Ten or Funnelify Unlimited consider buying the standard/main product from our sales page here: http://funnelify.com/fe/
