SDL Trados Compatibility and Migration Power Pack app

Hello All, 
I hope I am in the correct forum but if I am not maybe you could point me in the right direction. I am new to SDL Trados. I am trying to upload my glossaries and align my previous translations to SDL MultiTErm but I am not being successful. I think I am saving them and then I cannot find them, I am probably not doing it correctly. 
My question is:
Do I need to download the SDL Trados Compatibility and Migration Power Pack app from the app store? I am trying to do an alignment and save some translation memories and it says:
 "(No translation units to display.)" in SDL Trados Studio.
I appreciate any help you could give me. 
Thank you
