While we're working on a fix for this problem, here is what you could try:

  1. Shut down your DAW and Reason Rack Plugin.
  2. Go to %appdata%\Propellerhead Software\Reason and delete the "_Reasondata.prf" file.
    Or, if you are using Reason 11 Suite, go here:
    %appdata%\Propellerhead Software\Reason Suite and delete the "_Reasondata.prf" file.
  3. Launch your DAW and Reason Rack Plugin, and do NOT click the "Remember my password" box in the Welcome to Reason window if it appears.
