Cubase SX 3 Sylenth 2.2 Macbook (intel) VSTI unloadable

[Cryotech]

Guys,

I have a little problem. I downloaded the Sylenth demo. Just too watch if it's running on my sys. But unfortunatly the VSTi is not showing up in my plugin list. I'm runing Cubase sx 3 with sylenth 2.2 on a mac (intel).
When i look in my Plugin information tab Sylenth demo is brown and not showing any vendor etc.

Do you know any answer?

Regards,

Daniel
