Install USD in D365 Trial

Hi,

I would like to get familiar with USD in D365.

When I'm running the Package Deployer of the USD source, I am not prompted with my CRM Org - this is what I see:

- start the USD Package Deployer

- enter the D365 credentials

- for a glimpse (less than a second) I can see my D365 Org name, but than it disapperas again

- I am prompted with the login screen for the D365 credentials again

Are D365 trial Orgs qualified for the use with USD?

Thank you.

BR,

Tino
