Hello, I have the same problem with Sample tank as a plug-in within BiB.

Of course I can run Sample Tank as an administrator when opening it as a
stand-alone application, but not when I use it within BiB.
Does anyone knows how to solve the problem?

I take this opportunity to give my "discontent" about the programs from
IKMedia. I have not succeeded up to now to use Amplitube BOTH in BiB AND
in Music Creator 6. It is one or the other with every time a new installation.
All my question sent to IKMedia in this respect remained unanswered until today...
