Curve Eq in Cubase Artist 7.5

Hi

I have Cubase Artist 7.5. Recently my Voxengo Curve EQ plugin is coming up with an error message saying that the licence has expired and it seems to have reverted to a Demo version. Is this normal? How do make it fully functional again? It is saying that there is no licence for it on the USB e-licenser. Do I just purchase a copy from the Voxengo website? Or do I need to do something different to make it so that the e-licenser can ‘see’ the product?

Cheers
Simon

you need the regular cubase for this plugin… ?
