I'm afraid you can't. Even if you buy Scriptdio Club without the Standard Version, you will not be able to login.

Here is why:

1. Scriptdio Standard is the main product which is either a Monthly, Yearly or One Time Subscription.

2. Scriptdio Club is an Upgrade or Up-sell which adds the VIP Library Frameworks in your Scriptdio account.

3. Since Scriptdio Club is not independent, you will need to subscribe for the main product Scriptdio Monthly, Yearly or One Time subscription first. Else you can't login with only Scriptdio Club in your account.
