[Help]Level up problem!

Hi everyone, I need your help!
In my server, when character up level to 140, it cannot up level to 141, 142, 143....
Exp is 101% or 200% and more.
Must be logout account and login again, then, character's level is 141, 142...

Please tell me why? T_T

PS: Sorry, my english is very bad!!!

check ur formula.ini at both sides client and server probly ur client side has max lv 140 or something or check ur exp.csv might also have a problem there with the exps. ;)
