It's all cool. You're trying to point out how important critical thinking may be while reading other confusing guides and I can understand that. I'll take care to keep that in mind the next time I get stuck on another confusing guide someday. What I'm trying to point out this whole time is that I don't want to break my game just for overlooking a small step or so. I just don't want to end up like one of these guys that bring up a problem already addressed by the author and what to do with it simply because I never read or even try to because I expect everything to be on a silver platter like most people you'll often see on Nexus. I just want to be as loyal as possible when following instructions otherwise I'll feel as if I'm walking in the dark or shooting myself in the foot for embracing ignorance. I do this because unless I'm a skilled mod author or has a greater understanding of modding in general, the mod author of the mod I'm using is always the smart one.
It's still giving me errors after redownloading the patch file and rechecking its errors so I followed your instructions afterwards.
Is it like this?
I'm not sure if I'm following it correctly. This is after I checked the 'MLU - aMidianBorn Content.esp' file for errors in TES5Edit. Also, this may be slightly relevant but the current version for my Merge Plugins atm is v220.127.116.11
Now, please make sure that you are using the correct version of the aMidianborn Content.esp file. Check the STEP instructions, http://wiki.step-pro...Recommendations
you should use the Improved Closefaced Helmets version of the plugin.
Next, I'd like you to post another screenshot. Take one of the FormIds that showed an error and enter it in the FormId search box in xEdit.
Example: Your error check reports an error in [0009bc34]. Enter the number without brackets in the FormId search box end press [enter]. xEdit will show the record. Right click anywhere on the detailed record view and choose to hide no conflict rows. Post a screenshot. For me, it looks like this:
My error check reports no errors. Try to take a screenshot of one of the records that begins with 01, like [01089ee7]. These are especially interesting since they point to  Update.esm. The first to digits in the FormId (=record ID) points to the plugin that introduced the FormId (I am simplifying here). These first two digits are changed as the load order changes. They are in hexadecimal and are the reason that you cant have anymore than 255 (=ff) active plugins.
The plugin Update.esm always have the load order number  and is interesting cause other records can inject FormIds into it. An example of this is Weapons and Armor Fixes Remade (WAF). WAF introduces new keywords. Each keyword has a FormId. Any mod or patch that uses these new keywords would have to have WAF as a master plugin. To counter that, plugins that uses WAF keywords injects the keywords into Update.esm and Update.esm becomes the master plugin instead. This way, mod and patch authors can make their plugins with WAF keywords whether the user intends to use WAF or not. The important thing here is that the plugin that injects the records must have a keyword section that gets injected. If a mod or patch author forgets to add the keyword section and no other plugin in the load order contains them, you will get an error in  Update.esm.
I am not sure that is what is happening here but if you can get a screenshot from a  error too it would be helpful in finding out what is going on.
