Irregular Activity Crash

I used this tutorialhttp://www.mpgh.net/forum/487-dragon...t-dummies.html to multi client a few days ago and everything was working fine but today when i logged on to Dragons Nest (Without the multi client) I was given the message that Irregular Activity was detected and the game shut down.

I have already tried reinstalling the game to no avail..

BTW I tried using my account at a friends house and I had no problem so it's not my account.

I don't know, but I keep getting that crash, EVERY time I play. (NA version.) NO hacks/mods, just a straight install. Half-assed unstable anti-hacking software, if you ask me.
