Opening .dll format in Passolo and setting up the glossary

Hello, 

1) A client sent me the Passolo resources in a .dll format. How can I open them in Passolo? 

2) I have a termbase in SDLTB format. What's the best way to connect it to a Passolo project?

I am new to Passolo so I apologize if my questions are obvious. I am using Passolo 2016 Translator Edition.

Thank you

Ivan
