This has happened before but usually shutting off 'constrain delay compensation' has solved the issue in the past but not this time. Several waves plugins are blacked out as is Avox and several others. I wondered if some of the Geniuses here might be able to help out.

I uninstalled Cubase and reinstalled but the problem still manifests itself. I have looked at graphics drivers and souncard drivers and all are up to date. So i am totally flumuxed.

Any suggestions would be greatly appreciated.

 

if you still need help

cubase as of v9 has a so called Plugin Sentinel that Blacklists plugs that crash during startup
this is due to (as v9) vst bridging is removed from both CUb/NUendo.
Only 64bit VST 2&3!
You can under the plugin manager RE-Activateblacklisted plugs, one by one

3rd party bridging still works though
