I don't know if Nexon fixed the actual bug or not, but there is a way to fix the messenger problem (not being able to add friends, clan chat not working, etc.) You do not need to make a new account. Simply delete or uninstall your Combat Arms game and reinstall/redownload it. Again I don't know if Nexon fixed this themselves or not, so I apologize if everyone's messenger service is currently working and this topic is useless. If I helped anyone your welcome. PLEASE don't criticize or spam. Thank you.
