My Trados Studio 2017 does not allow me to choose the language-pair when I open a new project

Hello everyone,

The Translation Memory window does not pop-out when I open a new project; therefore, I cannot choose the language-pair. My Trados Studio 2017 automatically choose EN(US)-SP(Latam). I must have clicked the option of "do not show this window again", not sure. 

Does anyone know how I can "recover" this option, so I can choose the language-pair I want before starting translating a project?

Thank you in advance.

Regards,

Pablo G.
