Well... my problem is solved and (predictably) was totally my fault. So it didn't work outside of Mod Organizer either. I tried installing an older version of MP and it worked fine. Re-installed the current version in a different folder and it works fine both inside and outside of MO. I'm now sure I messed up the initial installation because when I first ran MP, it prompted me to create a "lang" folder and gave me a webpage to save as an English.lang file. I guessed that was normal, but I'm pretty sure I somehow only extracted the .exe. Really sorry for the headache, I should have cottoned on sooner. And thank you for your help and patience.

Hi again GrantSP, I created a new MO profile called "Merge Plugins Test". I made sure only the vanilla plugins were selected in the right-hand side plugin pane of MO. I ordered these Skyrim.esm, Update.esm, Dawnguard.esm, HearthFires.esm, Dragonborn.esm Then I ran Merge Plugins through that MO test profile and selected only the plugins above (leaving the High-Res Textures unchecked). The MP splash screen was still appearing to load Skyrim.esm indefinitely. So I closed Merge Plugins with Task Manager. I'm guessing I needed MP to get past that splash screen to access the Logs tab, but here's the vanilla attempt from the MO Log in case it helps... https://pastebin.com/G7MK2MuL I don't know if it's relevant - but these lines at the end were a full three minutes before I ended Merge Plugins with Task Manager...

Thanks so much for your reply. I hope this is right: https://pastebin.com/g56g6w4t I closed Merge Plugins down with Task Manager, but I can let it run longer if that would give a better log. Thanks again.

Hello. I'm sorry to report the same problem.
