Vista problem with a game

Hello

I'm having a problem with Vista 32bit and playing games with it. I had absolutely no problem with XP.

OK. The game i play is Kalonline. Right now, im trying to play on a different server which is vista compatible. The problem is - every 30 seconds im logged in, i get engine.exe(anti hacking problem). I even spoke to the gamemaster who sent me his version that works for him, but still, cant last more than 30 secs.

Thats the site. We tried everything, turning off antivirus and firewall(which is known to interfere with the hackshield), yet i still have the problem. Any help is appreciated, thanks!

 

Also to add on to my previous post.

Its nothing with the client, other vista users are able to use it fine, but i think some sort of program may be stopping it. I really dont know what it is, tried running as admin, etc.
