Hi David-
Sorry to hear that you are having problems with Studio One.
Are you able to successfully instantiate a new Octavox plug-in on your Windows version of Studio One? Is the issue only with this particular session pulled across from OSX?
You could also try the following steps:
1. Open Studio One on Windows, go to your VST preferences, and make sure "Scan at Startup" is checked.
2. Also click "Reset Blacklist" in the VST preferences, and then restart Studio One and open your session.
Let me know!
-Tom
