It happens to me at first then to my friend.
After reinstaled windows, I instaled ko, and auto patched.
But when i wanted to open it... Invalid data tables - error appeared.
People were saying me to reinstal ko and patch by myslef. It didnt help.
Problem was still actual. I have even reinstal windows again (from another CD to be sure that windows is OK). PROBLEM APPEARED AGAIN... I was confused.
Friends sent me good files which I exchanged. Seems to help but when i loged in to my character i cant move cuz it makes me disconnect!!!! I tried to do it again and again. NOTHING..
I was thinking ,,maybe there is something wrong with my computer'' :/
WASTE OF TIME!!
Then i went my friend.. I copy instaled ko folder and bring it to me.................
Working..... if u have similar problem, now u know what to do.. ty
