I upgraded computers recently re-installed BIAB 2018 Megapack off of the supplied USB flash drive.

I did the rebuild thing on the styles selector.

Then I loaded and old song and got a bunch of "style not found" "real tracks not found" errors.

The old computer showed over 4,000 styles.
New shows only 2,600 or so.

Question.......
Do I need to install all of my old version of BIAB first?
I have 2010, 2017 and 2018.

I also sent a note to techsupport

Thanks
