Running the above version of RM and my Kemper head has v 8.0.6.24597. Using Windows 10.
When RM is open, I get an "Oops! Something went wrong :(" message in the editor area and a "Rig Manager requires an update to show an editor" message as well.
When I try to update RM through the application, nothing happens. I downloaded the update and extracted it but when I try to run the installation, again nothing happens.
I guess the next step is to uninstall RM completely and reinstall, or am I missing something?
