If ASC says it's activated, then you can try to both Clean pref and Reinstall through ASC. You find the options in a popup menu, if you click the arrow right of the uninstall button for Pigments in ASC.
If it does'nt help, then perhaps this can be an activation issue of some sort. I suggest you contact Arturia support.
I don't know if Pigments 2 require more of the graphics. But if so, then Arturia can tell.
I see, that the envelopes displays also are empty.
If i suddenly get a new idea, then i will return. But don't exspect it. Please Contact Arturia support.
