Alternatively, messages in the system log may give some clue to the problem. You can view the log in the Console Utility.
Yes, you should contact MM tech support. Provide as much detail as possible - version of the software, version of OS X, any third-party audio plug-ins, audio hardware and drivers, etc.
You may also get some help in the Smart Music section of the forum. This section is for plug-in software development.
