Error in data preview with Salesforce Edition

I am trying to build some dataflows, but I get this message when I try to preview some of the data.

I thought the version we were using for trial was the full version. Can I get a different license key that will allow me to preview and transfer data from our internal CRM to Salesforce?
Is there a general line of Astera support?

The license we gave you is a trial for the salesforce edition. This is a restricted version that limits to what you can connect to. As the error states, all of your sources or all of your destinations must be salesforce connections.
Is this the case?
