So go and check the MMM folder you created. Are all .esp/.esm files directly inside it, or are some in sub-folders inside it? If some are in sub-folders then you need to move the files up to the main MMM folder. Similarly, if any of the "textures", "meshes", "Sound" etc. folders are within sub-folders, they must be moved up to the MMM folder too.
If you right-click on the omod and select "Edit omod" and then wait for the omod creation window again, you will see a list of all the plugins that are part of the omod. If any of those are listed within sub-folders, you have got it wrong.
Yes, it sounds like that. So check the folder structure and report back.
Indeed that was the problem. The sub-folders. I moved them all to the main folder and it didn't complain about sub folder or anything when I clicked "Create OMOD". It is compressing now and I am sure will get it.
Thank you for all your help!
