Hey Guys I know this is an old thread and I might be better served starting a new one but I wanted to give this a shot first. I am having a similar issue but let me explain how I got to this spot. I had a working copy of MO v 1_3_11 with a working modded copy of Skyrim, I attempted to use a steam mover to move the game and a manual process to move my MO folder over to an SSD, turns out that the SSD was exfat not ntfs and this messed things up so i'm starting over new with just my mods folder rared up as a backup. When launching MO I would just get the splash screen and it hangs there indefinitely, I uninstalled the app, removed all registry entry's and folders and reinstalled it in a new location fresh, no mods no profiles nothing, I have a new install of skyrim from steam in a new steam library folder nothing done to it but launch it once and let it detect video settings. I've excluded the Skyrim folder and the Utilities folder where I have the installer and have MO installed too, I launch it and still get just a splashscreen. Please help if anyone has any input, i'm pulling my hair out over this one.
