The status of this is now that PG has intervened and while we can identify that there is a problem there is no resolution via patch yet.

When I plugged in the hard drive (working again) and ran RB from there, I do not get that message. The style picker tells me I have 4,742 styles.

When I run the installed copy, I continue to get the "rebuild" message, and I have 4,741 styles. Since 4,742 does not equal 4,741, apparently RB has a "check the number of styles" function coded into it and when it is not 4,742 you get that message. I am not about to sit and compare the installed copy to the hard drive copy to find one missing style, but that seems to be my issue. The email I have in to them now is asking what I need to copy from the hard drive to the installed version to find that missing style and put an end to that message. If it's one specific folder I can do that easily. If it is individual files I will not likely mess with selecting 4,742 individual files to copy unless they are clearly marked with an extension (like ".sty") and they are easily selected. It would seem like if enough people have the issue, and that "extension method" mentioned above fixes it, it's a simple batch file to write.

copy g:\RealBand\*.sty c:\RealBand /y
copy g:\RealBand\*._sty C:\RealBand /y

As long as they are all called something consistent like stylename.sty or stylename._sty that will be a simple thing.

Watch the one I am missing be called stylename.goat and have nothing to do with "sty".... That would be my luck right there!
