Good advice Telecharge. I had some other types of issues with AD2 and the support team at XLN Audio was extremely helpful. Their response time was amazing!
Very interesting EJ Kelley....I get the same error message and ONLY when I am working with AD2. I have Sonar Platinum and I am running 16 RAM. I am not sure what is going on. I was going to contact XLN myself. Getting frustrated with making drum patterns (not complex) and SONAR shutting down. At first I thought maybe I had too many tracks going on so I started using a couple of Platinum's templates and still had the issue of the error. Sometimes it would take awhile for the crash other times almost immediately. I have only been at the SONAR game for a little while. Still learning. I have some songs that I want to record but, I don't want to get into them too far until I figure out the crash and get a bit more "learning" done.
