Okay for those of you disconnecting check and make sure you've done all of these steps below.
1. Make sure you've downloaded ALL components of the private server you plan on playing. For example, ECSRO servers requires you to download a client, pk2 files and media files.
2. For Vista users, make sure that you have compatibility mode on for the private server client. You can do this by right clicking on the client file>properties>Compatibility tab> and check the box that says 'Run this program in compatibility mode for WINDOWS XP Service Pack 2.
Hopefully this would help with some of your problems. Also I would like to refer those who have difficulty with the skills to check this thread out:
It has the force skills translated into English but the weaponry skills still remain in Chinese. At least this will help you out with which skills to add or not.
Let me also add the fact that you MUST login on the first try for the bot to work. Also if you've set everything up correctly and you press F6 and the bot doesn't auto attack, try clicking on a monster and let the bot attack. Usually this gets the bot in motion.
