While I'm aware that this post may be unwarranted, I would like to share something that I discovered while trying to install agbot.
I hadn't played SRO in over a year, so I had never used agbot before and was therefore trying to install it for the first time. For several days I searched for solutions to my problem where nuconnector would remain at the "Listening for bot connection" step and would never detect agbot or Silkroad. I tried all the solutions that I could find posted and was about to give up, when, out of sheer coincidence, I had to switch my "Support for non-Unicode languages" setting off. It had been set on either Russian or Japanese during the entire time I was trying to get nuconnector to work. As soon as I switched it to English, nuconnector suddenly worked.
I just felt that I should post this solution, since after a week of frustrating myself installing and reinstalling, I was about to give up, and I had never seen anything mentioned before about Regional and Language settings causing conflicts.
