My Memory plugin 2017

Yes, I saw the question was asked a few days back, but it doesn't help me. I am not using Memsource whatever that is.

 

I have worked with Studio for a number of years and been very happy to use My Memory as it is a great help. I have just changed from 2014 to 2017 and am about to start working on a large project. But although I attach My Memory to it, it doesn't deliver any suggestions, not even for segments with one or two plain words. Is it because I haven't chosen the professional version to be paid for?

I then tried to close studio 2017 and open my old studio 2014 instead, but no can do. I keep getting an error message there.
