I have Studio Trados 2015 SR3 12.3.526.0 and I had an error message when "preparing package to import" (from World server 10.1.0.207). The error is "Object reference not set to an instance of an object". Then I looked if I had installed SDL MultiTerm 2015, and I don't have it. I was looking for a way to download this component or any other component that I may need.
You don't need MultiTerm installed at all. The necessary components to handle a termbase are part of the Trados Studio installer. Please share the full error message you see when you click on the small disk symbol in your object reference error.
