Scaler 2 not working on Mac Logic 10.5.1

Was initially using scaler 2.0.1 and scaler was working fine on one song…

then i went to use it on another song and i could not get any audio to play or any midi to go through…
then went back to previous track to see it was not working at all anywhere.
figured i might have messed something up and seen there were updates so decided to uninstall and update logic x.5.1 and scaler 2.0.8…

there is still no audio coming from scaler or any midi going through…
it does not work as midi fx or as an instrument…

whenever i take it off the midi fx channel then then i get audio again from an instrument so i know the midi is working… just not through scaler…

Logic 10.5.1 rescans and resets all your AUs and VSTs so potentially a problem there. I would suggest. Reinstall Scaler 2.0.8. Reboot Mac. Open Logic, allow full scan. Check if Scaler is operating as expected otherwise Logic Pro X/Preferences/Plugin Manager search for Scaler 2 and reset and rescan selection.

Appreciate the quick respone!

Second option worked! After reboot too of course.

Any idea why it could have stopped working to begin with?

Logic 10.5.1 is rescanning all AUs so it is causing problems everywhere and with many plugs as they may have passed validation in a previous os but failing now. My scaler was fine.
