Hi, 
after updating my Sonar Platinum is stopping with no reason, and when I'm turning it on again I have message: there is no audio driver in your system while V Studio works with the system, Sonar does not see its driver...
 What do you think...

You may want to check your "Share Drivers with Other Programs" setting under drivers.  Make sure it is the same as your last Sonar install.  Also verify that you are using the VS-100's ASIO driver.

Hi, thank you for the answer:) I didn't make any changes with driver setup. I'm using ASIO driver. Now I see the reason is in Dimension Pro with guitar samples ( almost together and the last one from Gibson les Paul Gold Top- 12 string bright) . Sonar stops when I play or when I'm trying to freeze it.
