After launching the Xplorer Player you will be asked to select your Organization URL. This is the server that you will login to and access projects from. By default it will be connected to Modest Tree's public server: https://app.techcompanion.io/api/. You can use any Modest Tree account registered through app.techcompanion.io to login here. If you belong to an organization that has its own private server with Modest Tree you can change it to that one now, otherwise just hit continue.
If you belong to an organization that has its own private server with Modest Tree you can change it to that one at any time.
NOTE: if your organization URL doesn't follow the standard Techcompanion.io ending you will need to use the advanced edit by clicking the settings icon to the right of the textbox. This will allow you to edit the entire URL.
To re-connect to the original server you can click Reset to Default
