This issue happened a few hours ago.
The first time I tried to log-in, it said the Error
(You have lost connection with the server, please try again in a few moments. Error -100) Something like that.
The second time I tried to log-in, it logged in perfectly and fine the way it used to be, it was no the screen that says in the lower left corner (Loading messenger, etc).
And then after that Combat Arms just shuts down, saying no error, nothing. Having being shocked, I decided to go on my other account. It worked perfectly and fine.
I'm not sure if it would be fixed by tomorrow morning. Not sure, thats why I'm asking you.
Help would be greatly appreciated.
EDIT: I can login and it works now, thanks for helping, even though you guys didn't help really much
Have a good day.
