I upgrade all of 33 products of my V Collection 9 and MainStage & Logic can't start they remain in Audio Unit control mode and do not start up.
Even if I start the single tool it does not start.
Has anyone happened the same thing? And maybe you managed to solve the problem?
This thing drives me crazy also because I have to play tonight and now I'm remaking some sounds with other instruments.
On Sunday I sent a message to support but they still haven't answered me ...
