Neuz.exe is not responding

Hello,
I got a problem. I can play in the server for about 5 minutes. And then I suddenly get Neuz.exe is not responding and flyff closes. When I try to restart flyff I suddenly get the message: Cannot connect to the game. Please check the network. (When I want to go into world.)
I don't have any doubts my problem is the PC:
RAM: 3.8 GB
Video Card: ATI Radeon 4200HD (I know that's a bad one but good enough to play Flyff with.)
Processor: AMD Phenom x4 955 3.20 Ghz.

If anyone can help me. Thanks in advance,
FinalWingz

I'm going to guess that the Neuz.ini has stopped working is because of the Gameguard, However with no indication of Game Guard running I can only guess it's because of your firewall settings or, a anti-virus, or something has blocked the Neuz.ini access. If your using Vista then that is probably another problem, I know it might seem daft but try disabling visual effects by,

Start Menu > Control Panel > System > Advanced > Performance and click the check radio button for "Apply for best Performance" It's rumoured games don't like Vista's visual graphics.

same to me >.
