yo hise esto lo publicaron el ko4life Dendriod0s:
What i did for xtrap was, installed manually patch 1472 by extracting the file and replacing the old files, changed the "Files" number to 1472 in Server.ini found in the folder C:\Program Files\KnightOnline
[Version]
Files=1472 <---------- Change it from 1476 to 1472
then start the game and let xtrap download some files. Then manually install the patches 1473, 1474, 1475, 1476. If it didnt work try extracting patch 1476 straight after u after xtrap downloaded the files with patch 1472. And then replace the "Files" number.
[Version]
Files=1476 <---------- Chane it back to 1476
Worked for me on patch 1474, it should work again...
