Automated translation poorer with the 2017 version than with the 2015 one

Hello,

I have been trying both Trados 2015 and 2017 on the same project. At the begining I was working with the 2015 and then I switched to the 2017 version. To my great surprise the automated translation offered by the 2017 version is far poorer. Very often it offers no result where the 2015 version has a fairly good suggestion.

Maybe there is just something wrong with the settings of the 2017 version.

Could anyone help me please?

Thanks

David
