Piano Colours doesn't open fully in Kontakt 7?

Darkersound

Upgraded my NI Komplete to collectors Edition 14.

I've just installed Piano Colours. I've tried to open this with Kontakt 7 within Reason Studios 12.6 and it won't open fully. Although I can play what appears to be the initial patch and hear the sound - the instrument panel doesn't open within Kontakt 7 - I just get an endless spinning beach ball.

I've closed all software down and re-opened and just tried a restart on my MacBook Pro and the same thing happens.

Anyone have any ideas how to solve this?

MacBook Pro 2019 (Big Sur 11.7.6)

Reason Studios (12.6)

Kontakt 7.3.2

Darkersound

... resolved.

I opened Piano Colours in Kontakt 7 standalone mode and now it opens fine within Reason.
