Just found out about the program last night, fell in love, bought it so I am speaking from a position of ignorance, but...
When I bring up the MSG advanced editor, all I get is a blank window with "MSG Advanced Editor" in the title bar. I thought I probably needed to load something. I brought up the MSG presets and selected one - no change. I right clicked in the advanced editor window and selected "Import Preset", went and selected a preset from the presets in the program directory. The preset appears in the preset window and runs when I press the action button, but still nothing in the Advanced Editor window. I have suspicions that this may be because I installed a trial version before the retail version. When I tried to import the preset mentioned previously, it initially pointed me to the old "Studio Artist Trial" directory rather than the retail version's directory which seems a bit suspicious.
In any event, nothing I've been able to think of has gotten anything but a blank directory in the advanced editor. Am I doing something wrong?
