How do I get the Pro-trial?

Im a new user. I have downloaded and installed. But i didnt get the trial for the pro-version.
its still the free version.
How can I test the Pro-version with more that 2 accounts?

After you have installed eM Client, you can test it for 30 days with all features enabled. But once you have activated a Free license, you can no longer test the Pro features.

How can I deactivate it and start over?

You can’t go back to testing the Pro features once you have activated a Free license.

So you get 30 days to test the application with all features enabled, but once you activate a license, that evaluation is no longer available to you.

No eM client for me then.
