OK for some further clarification and a few more questions.

I didn't get it quite right with my explanation above.
I did restore my BIAB files a few days ago, but for some reason I forgot to restore perhaps the most important folder with 30G + of files. My Real Tracks folder!

So that explains why I wasn't seeing hardly any Styles to choose from.
That and also because the location pointer to my custom Real Tracks folder had been wiped as well.

Now that all my Real Tracks have been restored and the pointer is correct again a lot of Styles are available to choose from.

However, I was able to pull up a few really cool Styles yesterday (without the Real Tracks restored):
Vibes, Rhythm Jazz Sw 110
Vibes, Rhythm JazzBallad Sw 060
Vibes, Rhythm Jazz Sw 140

For some reason I can't see them now after I restored my Real Tracks!
Suggestions on how to get them back?
I saw them yesterday by choosing an instrument and selecting 'substitute Real Track for midi' etc.

Another question.
In order to see my Styles quickly and easily I would like to sort them according to header, in the Style Picker window.
However it is not sorting properly. If I click on Name or Long Name, I don't get the Styles sorted alphabetically.
