Vrs 1.8 compatability with Ableton Live 9

I sometimes use Scaler with Live 9 and up to now have not had issues. However I recently updated to Scaler vrs 1.8 and there seems to be a compatibility issue. LITE says that there is compatibility issue and has isolated the plug in. I then reverted back to Scaler vrs 1.1.7 and the problem disappeared. However it looks like 1.8 may have issues with Lite 9.
