Logic 7.0 doesn't see the Grand using FX VST to Audio?

[milles]

I upgradet my Logic 6.4 Expres to the 7.0 Expres. On the 6.4 version works the Grand Piano by Steinberg using FX VST To Audio ok. But the upgrade 7.0 can't see the Grand. I did a new configuration, but can't see it anyway. Does anybody know anything about this problem? The upgrade 7.0 does see the Intakt by Native instrument - VST too, and The Grand no? Why?

Surely, the workflow of Logic cannot benefit a musician. Overbloated with features, the Apple development team doesn't have time to fine-tune every single miniscule function of the software. Switch to a host developed by an independent developer; then I am sure you will NOT have this problem.
