C4D octane Material icon bug

[Abeperspiration]

Hi,
My C4D OCmaterial just get something wrong after using the LiveDB.
The octane material icon in C4D material tab just got noting like the picture I post.
It seem's "Render all materials" would not help this out.
And after that, all my octane material preview just gone. Even in the Node Editor....
And the material I create after that bug appear is just have the same problem. Even in a new project. It seems something wrong with my octane.

Hope you guys can help me out of this. Maybe just something I did wrong? Please let me know if you guys have any idea of this.
