I just had to chime in after reading through all that. I'm quite positive it's related to the New Prontera.
If so this link might help you; http://www.mediafire.com/download/7hcz6u9vl4vjhb4/newprontera.grf(Credits to Tokeiburu)
The whole post is on Hercules, you can search for it there, "What do you think about the new Prontera?" topic.
If that fails, I could provide you an automated client setup using 2013-08-07 for free, just send me a PM.
So yeah, I totally don't think Client Setup is all that confusing. With all the tools that are currently available (NEMO), it's actually pretty easy.
I understand that it can be frustrating at times, but to keep flaunting your "10 years of RO experience" doesn't help you one bit.
