If you are using a freelance license, you are NOT able to create a project with multiple languages- i.e translate from more than one language or into more than one language at any time.
Individual projects are only bilingual.
Sorry to correct you, but this is not true. The Freelance version can create projects in the same way as the Professional version, what it cannot is "create project packages".
... translate from more than one language ......
This is not possible anyway, regardless of the editor one uses. A Studio project always has only one source language.
