Need Help!!! Material Library doesnt show up

Hi Corona Team,

I am working with 3DS MAX and suddenly the Material Libary cant open.
Error message " Material Libary is not installed, I have install it again"

I installed it 20 times and it was always selected. It doesn’t work.

Hope you can help me.

Thanks in advance

Maybe you can try to install library in offline mod?
