Last reply to myself; The 2.0.8.2 install was fine till I exited the game, no errors, just could not restart, shutdown or run Task Manager. MO's process did not shut down, nor could it be forced to shut down. That was something new I had not seen yet. So, just like running DDU for your graphics drivers(Did that also), I removed any trace of Mod Organizer from "users\appdata\local" on the C drive, went to the three install locations for the MO 2 files and games mods. Deleted everything but modorganizer.ini, profiles and mod folders. Re-installed MO 2.0.8.3b "Portable". Fallout 4 ran fine, exited MO and all was well. Ran MO again, used "Loot" then "BodySlide" and the Creation Kit in the same session, received no errors, shut MO down, no errors. Go figure. This is on Windows 10, FO4 running fine and so far and no errors from Mod Organizer after running FO4.
