Firstly, make sure you are running Loupedeck 6.0.1.
If you find your SideshowFX profile fails on import with the following error:
Go to the Loupedeck marketplace and under the Plugins tab select the corresponding plugin (Lightroom, Premiere etc.) Click the install button.
For Premiere, go into Premiere preferences and in the Control Surfaces section, press Add and select the Logi plugin
If you still find Loupedeck doesn't recognize the application, go to the application dropdown and select Add Application.
