Problems loading Halion..

Maybe a question for the Cubase forum but anyway…

I’m using Halion SE at the moment and 50% of the time it won’t load properly. There’s no apparent reason other than switching Nuendo on and off. Halion loads fine but the samples don’t, I get glimps of distorted sound and when I try to load a new sample the message “program loading failed”.

This can change after one restart or it can go on for 4 or 5 with no other changes done.
