Im having the same problem, im re-instaling too see if it fixes
Use the CombatArms_Direct launch. Worked for me.
it works for me and i dont use directory launch
hax are patched as of today.
PERIOD.
(Except new ones)
Its not the hacks its just NExfail servers.
u got to computer, then the c shet, then ca, then nexon, then click on ca direct and it will work
I do the start from my nexon folder but even for me it says File Currupted blah crap....
nexon fails
