Is your computer plugged in?

Is your computer plugged in?
All I can think of is uninstall it, reinstall it in a new directory, set compatibility mode to windows xp, patch and then load it up.
If no joy, twiddle with the game settings.
I still haven't gotten it working, so if anyone has any ideas, I would still really appreciate some help. Especially since my desktop here isn't suited for running Neocron. (I only reactivated because of how well Neocron runs on my laptop compared to my desktop)
I have now also tried running it in windowed mode and in dx7.
Which version of vista you have, what is your hardware config, check that your drivers are updated! turn off antivirus, anti-spywares and try to run the demo... it might be a software messing with NC...
