Has it ever worked on the PB before?
I've never had it on there before... so no. I've installed PT Free (on OS9 boot vol) and that seems to be working. Spark XL 2.8 launches form the 'Unsupported' volume however the SonicWORX power bundle hangs with the message:
"This copy of sonicWORX was not installed correctly. Please use the original "installer" application to install the software again.
Please remember that using alternative System Folders requires to run the installer once per active System Folder."
Also I briefly get a Prosoniq 'startup screen' where you can see the progress bar at the bottom and reads "Version 2.6.0- Authorization type: Not present"
Soo... I'll probably just reinstall that one separately and see what happens there.
