combo problem

[sirtuyen]

hello i've just been starting to play on merc lately. I got this problem with my combo, it is fine on the first skill, but then it always miss on the second skill I use, whatever it is (of course i checked the skill cool down, and this isn't my first time playing cabal, i've been playing for more than half a year before on vietnamese server, so im pretty sure that my timing is right) so posting this here in hope that someone experienced this problem can give me a solution. thanks a lot.

im sure that there's nothing wrong with my keyboard (since it's my new laptop anyway) and if it's lag then I dont think I can even get my 1st skill done :(
and thank god it's not only me who got this bug, there's another too (http://forum.cabal.com/showthread.php?22307-Combo-missing-bug.-Please-help.) but no solution either :(
