When converting a doc into a bilingual doc SDL Legit in Trados 2017 returns "completed" but nothing happens.

When converting a doc into a bilingual doc SDL Legit in Trados 2017 immediately returns "completed" but nothing happens. Anybody else having the same problem? Any ideas how to fix it?

 

I am running SDL Trados Studio 2017 Freelance, version 14.0.5889.5 on Windows 10.
