Yes I was getting a message along with the crash and i'm not sure what the message says it's no in english o.0. but I changed my UAC like Choko said and now its working fine. Thank you Xylene, Choko, and Chuk for all your help =]
Oh and Choko i tried running two clients directly from the PsoBB application and the second client crashed the first client same as when I tried to run the first through online.exe adn the second through PsoBB application.
Well i just downloaded the full installer from www.phantasystaronline.net. I didn't see anything anything about different clients. i tried opening one with online.exe and a second from the PsoBB appplication and that caused the first one to crash.
