FIXED*
After hearing back from Propellerheads, they gave me the following instructions:
- Shut down Cubase and the Reason Rack Plugin.
- Go to %appdata%\Propellerhead Software\Reason Suite and delete the “_Reasondata.prf” file.
- Launch Cubase and create an instance of the Reason Rack Plugin, and do NOT click the “Remember my password” box in the Welcome to Reason window if it appears.
That appears to work…
