If you are still renting your Klevgrand plug-in, please make sure that you are signed into the Splice desktop client with an account that has a Klevgrand plan active before you open up your DAW to load the plug-in. While you are on the Rent-to-Own plan, the client needs to verify the plugin once every few days.
In order to resolve this issue, please follow these troubleshooting steps in exact order:
Close out of Splice
Close your DAW
Relaunch Splice and log into the account with the active Klevgrand Rent-to-Own plan
Open your DAW and launch the plug-in
If you are still having issues, please again close your DAW and reinstall the Klevgrand plug-in directly from the Splice app in the "Apps & Tools" section.
We also recommend you reinstall the Splice app. You can get the latest install here: https://splice.com/download
