This should disable/override the TOE, same as changing the driver setting, except just for the application itself.
Not gonna lie. I don't understand at ALL what any of this did, all i know is i followed it word by word and... got online on my main character for the first time in days. Usually I get 90000 error after about 20 seconds of logging in, but after doing this I logged in flawlessly.
Too early to tell if it's because of this or just a happy coincidence, but I encourage everyone to at least try this!!
