Hello.
You do not need to close the Maestro Control Center to use the VSA software. I responded to your thread here with details about getting the Maestro set up and working with VSA. Please try following those suggestions first. If you have problems, you can continue the discussion in your thread, since this one is about a different problem that existed in an older version of the VSA software. If you can provide more details about what you are doing and if there are specific terms or steps you are unsure how to do, I would be glad to help clarify.
