Not really an answer, but a suggestion: try removing/uninstalling your new libs, then see if Giga rebuilds correctly.
If not, first uninstall, then reinstall Giga. (Don\'t just copy over the old copy.) Have it again search the libraries. If all is OK, go on, if not, yoj may have to start iver (reinstall OS, then Giga, then libs.)
When it\'s OK with what you previously had working, go on.
Try installing just one of the new libs (LOP, perhaps, NOT GOS, that\'s too many CDs for this test. If it\'s OK, move on, else it\'s Tascam help line time.
Cotinue installing new libs, run Quicksound update after each. Save GOS for last. If it allows this, just install 2 or 32 CDs at a time, updating after each. If it doesn\'t like that, then jump in and pray.
Like I said, not really an answer, but a workaround unless someone has a better idea (Killerbob? You reading this?)
