Just a follow up for those who read/replied if interested:

Apparently, there was some sort of compatibility problem with BIAB 2018 and it wouldn't run with Vista (and maybe with XP). PG Music fixed the issue with the latest build (505 I think).

It now runs on my old Vista computer without any problems that I've encountered. It was worth the hassle to get it to work so I could use the real tracks and other features new since my 2005 version.

Thanks to those who replied and to PG Music for their quick response to fix the problem.
