The I: Drive is a physical HDD. I deleted the game through Steam then tried to reinstall to check if the path in that error was generated. *EDIT* Great news! After deleting everything, I went to "C:\Users\Owner\AppData\Local\Skyrim" and renamed Skyrim to something else, restarted Skyrim to see if it would regenerate it, I used a direct TES5Edit exe within the main Skyrim folder (now with administrator privileges) through MO, went through the STEP instructions and it worked!
For whatever reason it took find a way to force skyrim to regenerate the folder for it to find the path.
Thank you so much for your help, I truly appreciate it. I can finally sleep easy without this driving me mad.
