So, I identified a previous 3.71.* or 3.72.* M-PC install may cause leftovers that prohibit the latest beta from working. Here’s an adjusted procedure for trying to make it work:
- uninstall the beta
- uninstall the Obsidian Driver Package
- install the latest M-PC 3.71 you tried/used earlier (if you don’t have it anymore, download it from https://obsidiancontrol.box.com/s/jydipnhmek05dzxzkqj19hfr97zv0w1c)
- uninstall M-PC
- install the beta
