[Plugin: Paypal Subscription Button] Can I make a FREE Group with this plugin?

Hello Developer!

Before I start to use your plugin I would like to know one important thing:

– I would like to protect one of my page on my wordpress site, which page contains downloads.

But I would like to access it to every registered member for a specified time (For example 2 days) in order to these members can test my downloads and if they like it, they can subscribe to a payment group to access downloads unlimited.

So is that possible with your plugin, that I make a Free group where my member can access my page for 2 days for free and when time is expired then this content will be protected from them?
