thank you guys, TheKnight & Amarisa,for your help!!!
but i think i got a problem which heavier to solve!!
here's the system details i currently use due to unfortunately things:
[b]Celeron CPU 2.26 Ghz
Memory: 504 mb ram
videocard: Intel (R) 82865G Graphics controller
Memory: 96 mb (rockin'!!

)
Direct 3D works of course[b]
SRO requesting user information at login for a 6-7 sec then disconnect me. I know, when SRO was let me in before, it didn't requested user information for long. Exactly it requested for a sec. And the screen was fade in to black, i was in. Now the screen didn't fade in with black color, never.I once got a msg: "Failed to connect server (c9)"
What could be wrong? The fading in at the login screen, is it related to the videocard or to something else?? Pls help!!!
