MULTITERM I Cannot Add Terms in SDL MultiTerm

 Good morning,

Hello, I have Multiterm and Trados freelance+ 2017 installed on a 64bit Windows 10 machine. when I try to insert a term in the termbase while translating (I'm using SDL Trados Studio 2017) Termbase viewer opens in the editor view butI just see a blank page, the terms are on the left but there are no information on the right. 

 

May you help me please?
