I am sadly very bad at remembering the different signs for different bugs..
But we can go through the basics
Have you checked that your firewall isnt blocking the client?
Location of your install? If it is installed in the Program Files folder it can be quite annoying. Move it to C:\Neocron or something like that instead.
I do find it kind of weird that you see Titan as 0% though..
Hopefully if none of this helps you out, someone who is better at remembering this stuff can help you out.
EDIT: Hmm maybe some people are having some problems actually.. Riddle has just made this thread:
