I somehow corrupted the link between the termbase and Multiterm. I cannot exit the termbase search (Termbanksuche in German) and open the terminology search. The terms found are marked with the red line but I cannot look them up. What went wrong with my various trials? Apart from that the result of these trials is that the Multiterm box is not shown at all. Apparentlich I destroyed some basic settings which I just cannot repair.
Thank you for your help!
