I am using the built-in help function to auto-update.  The update is found and downloads to the PC.  However, as soon as it finishes downloading, a pop-up indicates there is a new update found and stops all update functions.  I've tried to manually patch Movie Edit Pro 15 by going to the Support Web Site; downloading the patch and executing directly.  When this is attempted, the patch EXE responds by indicating Movie Edit Pro is not installed; and prompts to install via the CD.  Obviously, if I intially tried to patch via the auto-update within the Studio GUI, I have Movie Edit Pro 15 installed.  What's next?
