Changing email in free account?

I set up the free license using one email domain, but I want to see how emclient handles another domain before deciding to commit to a paid license. Is this possible?
Since I did not use emclient for a while, I am currently asked to reactivate my former free license now expired, it looks like.
But this would be a good time to try out the other email domain. So what are my actual options here? Do I need to remove the current desktop software and start from scratch? Is there a problem or not with having more than one free license?

You can add two accounts to a free license past the initial 30day trial, unless your free license has become deactivated due to some problem within eM Client on your computer.

Try going to “Menu / Help / License” and check it’s still activated. If it is already activated, try deactivating it and then reactivating it. Then try adding your second email address again.

If it’s deactivated, then try activating it with your original registered email address. If you have forgotten your free license, go to the following page to get it resent. You can then access that via your webmail and then copy and paste it into eM Client.
