Play v5 and v6

Sorry to misguide you I am using EWQL Symphonic Choirs. I bring up the UI from the drop down list of VSTs in the Play set up and proceed from there. After setting up the required word/phrase I record from Write. I downloaded Play 5, [not sure what this is], from a link in a previous thread - maybe benwiggy!- got confused with the UI now back with Play 6.1.9. Been a basic Sib user for a few years, not well up on what is going on behind the screen so I am probably making some kind of basic error.
