Thanks Garry. Unfortunately, the Preferences file isn’t as easy to find using Parallels. There is no AppData folder in my users folder within C: drive. Is it a hidden folder that requires a workaround to be visible?
EDIT: I found it by searching directly for the file name. Deleted the xml, saved a preference in MMH8, but when I launched MMH9, it didn’t move over the preferences. Tried uninstalling MMH9 altogether then re-downloading, but got the same result. And now MMH9 is back to alerting me about an available update, even though I’m already using Beta 3. Ugh.
