So, I bought something from PG website (for the curious, I bought RealDrums Set 20: LA Pop Jazz, because who can resist drums that evoke Steve Gadd's work on Aja?)...but this purchase has nothing to do with my question..simply setting the stage here...

and anyway, so I went to the download page, and saw with that order another available download:

Bonus: "Registration Bonus" RealStyles for Band-in-a-Box (2017 and higher)

My question is, seeing as how it says "2017 and higher" and being that I only have BIAB 2015, "is it going to hurt anything" to install these "bonus" styles to see if some of them might work? What should I know about compatibility, in this case? What would keep the styles from working in, say, the version I have?
