Maybe a reinstall of C6 will do the trick? As for the signature, it can’t be done inside the forum. You have to go to MySteinberg and there select ‘forum’.
I am not sure But I Advice you to update the License database within eLCC
If that doesn’t do the Trick Maybe Validate License Usage Periods Might do the Trick
I had A Similar Problem When trying to start VST SIS HSO in HALion sonic within Cubase 6
And after doing this it doesn’t give the error anymore
So the Problem Might be that the License Database is not up to date and doesn’t support Cubase 6 yet
or something Like that …
If you keep getting this error I advice you to contact Steinberg by use of your MySteinberg Account
I understand that Installing the latest version of eLCC seems to solve the problem
However Some People were not able to post this here after there Registration of Cubase 6
So I Like to advice the People at steinberg HQ to take A Look into this Little Forum Related Problem as well
